description: A MoS2 concentration gradient coating of an osteoarticular-like structure with efficient strain transfer efficiency was prepared on titanium alloy via multiple plasma electrolytic oxidation. This structure facilitates efficient strain transfer by dissipating compressive and shear strains via dislocation annihilation and MoS2 interlayer sliding, thereby preserving a strain gradient. Leveraging this mechanism, the coefficient of friction was reduced by 50.2% compared to graphene coatings, while the frictional stabilization time was extended by 160% about Single MoS2/TiO2. This study elucidates the dislocation behavior and the mechanisms of strain transfer during friction within this structure. The concentration gradient coating demonstrates prolonged anti-friction properties by establishing strain gradients through dislocation annihilation during friction, thereby facilitating efficient strain transfer.

description: Lattice spinor gravity is a proposal for regularized quantum gravity based on fermionic degrees of freedom. In our lattice model the local Lorentz symmetry is generalized to complex transformation parameters. The difference between space and time is not put in a priori, and the euclidean and Minkowski quantum field theory are unified in one functional integral. The metric and its signature arise as a result of the dynamics, corresponding to a given ground state or cosmological solution. Geometrical objects as the vierbein, spin connection or the metric are expectation values of collective fields built from an even number of fermions. The quantum effective action for the metric is invariant under general coordinate transformations in the continuum limit. The action of our model is found to be also invariant under gauge transformations. We observe a "geometrical entanglement" of gauge- and Lorentz-transformations due to geometrical objects transforming non-trivially under both types of symmetry transformations.

description: Studies of Neoproterozoic granites near the western margin of the Yangtze Block provide new evidence on the mechanism leading to the Neoproterozoic break-up of the Rodinia Supercontinent. This contribution focusses on the structural geology, geochemistry, zircon U-Pb geochronology, and Hf-O isotope systematics of the poorly documented Mojiawan Monzogranite in the Kangding Complex, which gives us better constraints on the break-up of the supercontinent. Zircon U-Pb data show that two samples of the Mojiawan Monzogranite were emplaced during 797 ± 13 Ma and 785 ± 11 Ma (ca. 791 Ma). The granitic samples are Na-rich, calc-alkaline, peraluminous with A/CNK values of 1.13 and 1.25, and their zircons have positive εHf(t) values between +4.28 and +9.79 with crustal model ages TDM2 of 1424 to 1079 Ma, indicative of a juvenile source. The granitic samples also have low Rb/Sr and Rb/Ba ratios and high δ18O values of 5.42‰–8.97‰, consistent with derivation from the partial melting of the lower to middle crust. Combined with the geochemistry of other granitic plutons along the western margin of the Yangtze Block, we propose that the region records rifting at ca. 800 Ma due to the action of a mantle super-plume leading to the break-up of the Rodinia Supercontinent.

description: All transiting planets are at risk of contamination by blends with nearby, unresolved stars. Blends dilute the transit signal, causing the planet to appear smaller than it really is, or produce a false positive detection when the target star is blended with eclipsing binary stars. This paper reports on high spatial-resolution adaptive optics images of 90 Kepler planetary candidates. Companion stars are detected as close as 0.1 arcsec from the target star. Images were taken in the near-infrared (J and Ks bands) with ARIES on the MMT and PHARO on the Palomar Hale 200-inch. Most objects (60%) have at least one star within 6 arcsec separation and a magnitude difference of 9. Eighteen objects (20%) have at least one companion within 2 arcsec of the target star; 6 companions (7%) are closer than 0.5 arcsec. Most of these companions were previously unknown, and the associated planetary candidates should receive additional scrutiny. Limits are placed on the presence of additional companions for every system observed, which can be used to validate planets statistically using the BLENDER method. Validation is particularly critical for low-mass, potentially Earth-like worlds, which are not detectable with current-generation radial velocity techniques. High-resolution images are thus a crucial component of any transit follow-up program.

description: Squeezed states, a special kind of entangled states, are known as a useful resource for quantum metrology. In interferometric sensors they allow to overcome the "classical" projection noise limit stemming from the independent nature of the individual photons or atoms within the interferometer. Motivated by the potential impact on metrology as wells as by fundamental questions in the context of entanglement, a lot of theoretical and experimental effort has been made to study squeezed states. The first squeezed states useful for quantum enhanced metrology have been proposed and generated in quantum optics, where the squeezed variables are the coherences of the light field. In this tutorial we focus on spin squeezing in atomic systems. We give an introduction to its concepts and discuss its generation in Bose-Einstein condensates. We discuss in detail the experimental requirements necessary for the generation and direct detection of coherent spin squeezing. Two exemplary experiments demonstrating adiabatically prepared spin squeezing based on motional degrees of freedom and diabatically realized spin squeezing based on internal hyperfine degrees of freedom are discussed.

Stories of Teaching Force and Motion: A Narrative Inquiry into Pedagogical Content Knowledge of Science Teachers
Creators: name: Azam, Saiqa
Publisher: name: Graduate Studies
Year: 2015
Subjects: subject: Education--Curriculum and Instruction
subject: Pedagogical Content Knowledge, Narrative Configuration, Science Teachers' Knowledge

description: Since the concept of pedagogical content knowledge (PCK) was introduced in the 1980s, many researchers have tried to elaborate this concept. This project establishes that understanding topic-specific science PCK diverges from understanding the broader PCK construct. It provides a conceptual framework that can be used to represent both general PCK and topic-specific science PCK. The research demonstrates how this framework can serve as a heuristic to consider science teachers’ PCK. The research explored how four experienced secondary school science teachers describe their experiences of conceptualizing and teaching the topics, force and motion. The aim was to access teachers’ thinking about using content knowledge and pedagogical knowledge to teach science content. Two narrative methodologies suggested by Polkinghorne were employed: narrative analysis and analysis of narratives. Science teachers’ descriptions were developed into (a) narrative configurations that portray their PCK—stories of teaching force and motion, and (b) PCK tools—teaching, learning and assessment tools that can be used to engage pre-service science teachers to help them develop their science PCK. Participant teachers’ PCK was organized using ten teacher knowledge components: (i) knowledge of content, (ii) knowledge of student learning, (iii) knowledge of instructional strategies, (iv) knowledge of teaching resources, (v) knowledge of technology, (vi) knowledge of science curriculum, (vii) knowledge of goals, (viii) knowledge of teaching contexts, (ix) knowledge of assessment, and (x) knowledge of student diversity. Each PCK component further contains knowledge elements, which are narrative fragments—events and incidents described by participants about teaching a specific science topic, pointing to the narrative nature of PCK. Each teachers’ PCK represents their professional and practical knowledge of teaching science. Participants’ knowledge can be further considered using a four-level continuum from general to topic-specific science PCK. This shows that content knowledge understanding is integrated with the other teacher knowledge categories.

description: We report the interception of two titanium hydrides in bulk Ti via additive manufacturing (AM) of hydride-de-hydride (HDH) Ti powders with high H content: nano-sized, stable face-centered cubic (FCC) δ-TiHx plate within α-Ti grains and ultrafine, metastable face-centered tetragonal (FCT) γ-TiH aciculae crossing adjacent α-Ti grain boundaries. Remarkably, the AM bulk Ti achieves a surprising balance of strength and ductility, surpassing those of AM bulk Ti and TC4 alloys. This balance is attributed to effective work hardening from {111} twinning in the FCC δ-TiHx plate, a hindrance to dislocation motion, and high-density dislocation pile-ups around the FCT γ-TiH aciculae dowel connectors. The nano-sized stable δ-TiHx and ultrafine metastable γ-TiH are intercepted by AM in bulk Titanium, providing a new insight into the microstructure design of metallic materials with exceptional mechanical properties.

description: The FeynArts model file MSSMdreg2dred.mod implements MSSM transition counterterms which can convert one-loop Green functions from dimensional regularization to dimensional reduction. They correspond to a slight extension of the well-known Martin/Vaughn counterterms, specialized to the MSSM, and can serve also as supersymmetry-restoring counterterms. The paper provides full analytic results for the counterterms and gives one- and two-loop usage examples. The model file can simplify combining MSbar-parton distribution functions with supersymmetric renormalization or avoiding the renormalization of epsilon-scalars in dimensional reduction.

Candidates with large pair annihilation rates are favored, suggesting a connection with the anomalies in the lepton cosmic-ray flux detected by Pamela and Fermi. Focussing on supersymmetric models we will consider the impact of non-thermal production on the preferred mass scale for dark matter neutralinos. We have also developed a new formalism to solve the Boltzmann's equation for a system of coannihilating species without assuming kinetic equilibrium and applied it to the case of pure Winos.

Assessment of cumulative effects of urban and agricultural land uses on indicators of water and stream quality
Creators: name: Wilson, Julie Elizabeth
Publisher: name: University of British Columbia
Year: 2011

description: This study assessed the cumulative effects of intensive urban and agricultural land use in Marshall Creek, B.C. The focus was to document how groundwater from the Abbotsford Aquifer and surface water from urban and agricultural tributaries contribute to cumulative stream quality downstream. Landscape stressors such as livestock numbers, Total Impervious Area (TIA) and human population numbers were related to the quality of water, bed sediment, suspended sediment and biofilms. Biofilms and suspended sediments were selected to provide an integrated indicator of potentially bioavailable contaminants. Nitrate-N concentrations in Marshall Creek are strongly influenced by groundwater discharges from the Abbotsford Aquifer, which has elevated nitrate-N concentrations due to non-point source agricultural activities. Nitrate decreased in the downstream due to significantly lower nitrate-N inputs from the tributaries (M-W U, p<0.015). In contrast, Soluble Reactive Phosphorus (SRP) and TOC increased downstream from agricultural runoff. Cu, Mn and Zn have increased in bed sediments in Marshall Creek since 1993. P concentrations have not changed markedly over time, but are significantly higher at the mouth than in the headwaters. SRP, NH4+-N, Cl-, turbidity and TOC were significantly higher in water in the agricultural tributary than the urban tributary (M-W U, p < α=0.0167). Differences in bed sediments, suspended sediments and biofilms showed that concentrations of P were significantly higher in the agricultural tributary than in the urban tributary (M-W U, p < 0.001), which is the result of nutrient and organic inputs from manure in the agricultural subwatershed. Biofilm chl-a and trace element concentrations were significantly different between sites and seasons. In the summer, chl-a and P were highest in the agricultural tributary, whereas in the winter chl-a was highest in the urban tributary due to warmer water temperatures in urban runoff. Trace element concentrations (e.g. Cu, Ni, P) were significantly higher in suspended sediments than in bed sediments or biofilms at all sites as a result of the higher surface area and greater organic matter associated with fine suspended sediments. Current agricultural activities are key contributors to the cumulative effects observed on Marshall Creek. Thus, improved livestock density and manure management practices are needed.

description: This paper reports follow-up photometric and spectroscopic observations, including warm Spitzer IRAC photometry of seven white dwarfs from the SDSS with apparent excess flux in UKIDSS K-band observations. Six of the science targets were selected from 16,785 DA star candidates identified either spectroscopically or photometrically within SDSS DR7, spatially cross-correlated with HK detections in UKIDSS DR8. Thus the selection criteria are completely independent of stellar mass, effective temperature above 8000 K, and the presence (or absence) of atmospheric metals. The infrared fluxes of one target are compatible with a spatially-unresolved late M or early L-type companion, while three stars exhibit excess emissions consistent with warm circumstellar dust. These latter targets have spectral energy distributions similar to known dusty white dwarfs with high fractional infrared luminosities (thus the K-band excesses). Optical spectroscopy reveals the stars with disk-like excesses are polluted with heavy elements, denoting the ongoing accretion of circumstellar material. One of the disks exhibits a gaseous component - the fourth reported to date - and orbits a relatively cool star, indicating the gas is produced via collisions as opposed to sublimation, supporting the picture of a recent event. The resulting statistics yield a lower limit of 0.8% for the fraction dust disks at DA-type white dwarfs with cooling ages less than 1 Gyr. Two overall results are noteworthy: all stars whose excess infrared emission is consistent with dust are metal-rich; and no stars warmer than 25,000 K are found to have this type of excess, despite sufficient sensitivity.

description: We present a new approach to factor rotation for functional data. This is achieved by rotating the functional principal components toward a predefined space of periodic functions designed to decompose the total variation into components that are nearly-periodic and nearly-aperiodic with a predefined period. We show that the factor rotation can be obtained by calculation of canonical correlations between appropriate spaces which make the methodology computationally efficient. Moreover, we demonstrate that our proposed rotations provide stable and interpretable results in the presence of highly complex covariance. This work is motivated by the goal of finding interpretable sources of variability in gridded time series of vegetation index measurements obtained from remote sensing, and we demonstrate our methodology through an application of factor rotation of this data.

description: In the request for sustainable development in complex components manufacturing, designing room-temperature high-plasticity material with simpler alloys becomes paramount. Here, pure aluminium composed of homogenously equiaxed grain was achieved by wire-based friction stir additive manufacturing, exhibiting an ultimate tensile strength of 143 MPa and a uniform elongation of 52.1%. The significant enhancement in plasticity was attributed to the equiaxed grains sustaining huge plastic strains via grain boundary sliding and grain rotation. Dislocation/disclination motion was discovered for the activation mechanism of the grain boundary sliding and grain rotation. This discovery advances the tailoring approach to developing large-sized materials with higher plasticity.

description: For further understanding of the molecular absorption mechanisms of photothermal conversion by coordination compounds, two newly prepared xanthene-functionalized silver(I) complexes, [Ag2(X9A)2(dppm)2] (1) (where dppm = bis(diphenylphosphino)methane and X9A = 9H-xanthene-9-carboxylato(-1)) and [Ag4(X9A)4(dppm)2]·6CH3OH (2), have been isolated and structurally characterized. We report here the syntheses, crystal structures, characterizations by various spectroscopic (IR, UV–Vis, powder XRD) techniques, as well as photothermal conversion performance of 1 and 2. Their X-ray crystal structures reveal that 1 is a binuclear silver(I) coordination compound bridged by two dppm molecules with two monodentate 9H-xanthene-9-carboxylato(-1) ligands, and 2 can be described as the dimer of 1 bridged by two 9H-xanthene-9-carboxylato(-1) anions in the μ3-η1,η2 coordination mode. Their photothermal conversion experimental results give new insight into understanding the molecular mechanisms for improving the performance of photothermal conversion molecular materials.

description: We use numerical simulation to examine the possibility of a reversible liquid-liquid transition in supercooled water and related systems. In particular, for two atomistic models of water, we have computed free energies as functions of multiple order parameters, where one is density and another distinguishes crystal from liquid. For a range of temperatures and pressures, separate free energy basins for liquid and crystal are found, conditions of phase coexistence between these phases are demonstrated, and time scales for equilibration are determined. We find that at no range of temperatures and pressures is there more than a single liquid basin, even at conditions where amorphous behavior is unstable with respect to the crystal. We find a similar result for a related model of silicon. This result excludes the possibility of the proposed liquid-liquid critical point for the models we have studied. Further, we argue that behaviors others have attributed to a liquid-liquid transition in water and related systems are in fact reflections of transitions between liquid and crystal.

description: Investigations on steel fiber reinforced concrete (RC) beams in torsion show, that the steel fibers positively influence the torsional load-bearing behavior. Since a systematic evaluation of the previously known test results and the derivation of a generally valid design model were lacking until recently, current codes such as Model Code 2010 do not contain any design models for the consideration of the steel fiber load-bearing effect in the torsion design. Due to this, the existing torsion tests on steel fiber RC were summarized in a database. Furthermore, on the basis of the test results and observations, the space truss model developed by Rausch and later refined by Lampert and Thürlimann, among others, was further developed and supplemented by additional longitudinal and transverse steel fiber tension struts. This modified space truss model was validated with the database and shows good to very good predictions to the torsion test data.

Merger by Migration at the Final Phase of Common Envelope Evolution

Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: I find the common envelope (CE) energy formalism, the CE α-prescription, to be inadequate to predict the final orbital separation of the CE evolution in massive envelopes. I find that when the orbital separation decreases to ~10 times the final orbital separation predicted by the CE α-prescription, the companion has not enough mass in its vicinity to carry away its angular momentum. The core-secondary binary system must get rid of its angular momentum by interacting with mass further out. The binary system interacts gravitationally with a rapidly-rotating flat envelope, in a situation that resembles planet-migration in protoplanetary disks. The envelope convection of the giant carries energy and angular momentum outward. The basic assumption of the CE α-prescription, that the binary system's gravitational energy goes to unbind the envelope, breaks down. Based on that, I claim that merger is a common outcome of the CE evolution of AGB and red super-giants stars with an envelope to secondary mass ratio of (M_env/M_2)>~5. I discuss some other puzzling observations that might be explained by the migration and merger processes.

description: In this study, Ni40Co18Cr18Fe14Al5Ti5 high-entropy alloys (HEAs) with a near-equiaxed grain structure and cellular substructures, devoid of significant microstructural imperfections, was produced via selective laser melting (SLM). The absence of brittle precipitates or substantial processing defects, which typically serving as fracture-weakening origins, allowed for effective activation of dislocation motion, deformation twinning, and stacking faults ahead of the crack tip. These mechanisms contributed to exceptional impact toughness (∼1600 kJ/m2) and dynamic crack initiation toughness (∼1000 kJ/m2). With an impressive yield strength (∼810 MPa), our SLM-produced HEA demonstrates a unique combination of impact toughness and strength that surpasses current additively manufactured metals.

description: Platinum-refractory ovarian cancer is considered an incurable disease as current treatments are only palliative. Improvements in treatment will be realized as our understanding of the unique signaling pathways driving disease development increases and new therapeutics targeting these pathways are developed. It’s important to recognize, however, that at this time new molecularly targeted agents are not replacing the drugs being used to treat cancer; they are being used in combination with existing standards of care. In light of this, it is important to explore novel approaches using existing agents that are designed to achieve maximum therapeutic benefits in dosage forms that are well tolerated. Like most cancers, ovarian cancer is treated with a combination of drugs selected on the basis of complementary mechanisms of action and non-overlapping toxicities. Synergistic drug combinations can achieve therapeutic effects equal to that achieved with single agents, but at significantly lower and better tolerated doses. The factors that govern synergistic drug:drug interaction are, however, poorly understood and it is argued in this thesis that drug interactions favoring synergy will be influenced by drug exposure time. An effective method to enhance drug exposure time involves the use of drug carriers and a goal of this thesis was to develop an effective combination regimen against recurrent ovarian cancer using a novel lipid nanoparticle (LNP) formulation of topotecan and Doxil®; a LNP formulation of doxorubicin that has already been approved for the treatment of relapsed ovarian cancer. The LNP formulation of topotecan developed through this thesis research, referred to as TopophoreC™, was 2-to-3-fold more toxic than free topotecan, however this product candidate showed significantly better anti-tumor activity when compared to free topotecan administered at equivalent doses. Combinations of this LNP topotecan formulation with Doxil® were therapeutically superior to combinations of free topotecan and Doxil® as judged in two models of ovarian cancer. On the basis of these studies, it can be concluded that interaction between TopophoreC™ and Doxil® affect the pharmacokinetic behavior of Doxil® however the results provide proof of concept data to support the use of TopophoreC™ and Doxil® combination for treatment of recurrent ovarian cancer.
The socialized will: Deduction of the question whether Duke Ulrich I of Württemberg (1487–1550) had “rightful power or permission” to “testify, create, order or dispose” his succession?

description: Wills are an indispensable source for historical research. They provide insights into early modern life. Princes’ wills are regarded as a source for the study of early modern politics and, more recently, of aristocratic communication and self-positioning. The contribution would like to broaden the view, to understand the dispositions of princes as historical snapshots with the help of which transfers of property and dominion at the beginning of the sixteenth century can be illuminated as situational and constellationrelated processes. At the center of the considerations are Ulrich von Württemberg and his plans to hand over the duchy to his half-brother and their legal appraisal by the Nuremberg legal scholar Franz Frosch (1490–1540).

description: We consider knot invariants in the context of large $N$ transitions of topological strings. In particular we consider aspects of Lagrangian cycles associated to knots in the conifold geometry. We show how these can be explicity constructed in the case of algebraic knots. We use this explicit construction to explain a recent conjecture relating study of stable pairs on algebraic curves with HOMFLY polynomials. Furthermore, for torus knots, using the explicit construction of the Lagrangian cycle, we also give a direct A-model computation and recover the HOMFLY polynomial for this case.

How Rising Sea Levels Affect Drinking Water in Sweden

Subjects: Geology not elsewhere classified

description: As a result of global climate change, sea level rise (SLR) is increasing at an alarming rate. In response to increased atmospheric temperatures, glaciers and ice sheets are melting faster than they can be constructed. This means that more water is entering the oceans, which contributes to an increase in sea level. As the ocean warms, its volume increases due to thermal expansion. These two processes play a significant role in SLR. At the same time, land uplifting in the north of Sweden still rises about 1 cm per year, while the land uplifting in the south is much slower and makes SLR more noticeable. This could significantly impact millions of people's ability to obtain clean drinking water. The coastal regions are particularly vulnerable to the effects of SLR, as they are more likely to experience saltwater intrusion and coastal flooding. This can lead to a shortage of clean drinking water, public health issues, and economic disruptions. Studying the effects of SLR on drinking water in Sweden helps to understand their risks and develop strategies to mitigate them. These strategies include implementing coastal protection measures, improving water management infrastructure, and finding alternative drinking water sources.

description: Travelling waves of densities of binary fluid mixtures are investigated near a critical point. The free energy is considered in a non-local form taking account of the density gradients. The equations of motions are applied to a universal form of the free energy near critical conditions and can be integrated by a rescaling process where the binary mixture is similar to a single fluid. Nevertheless, density solution profiles obtained are not necessarily monotonic. As indicated in Appendix, the results might be extended to other topics like finance or biology.

description: Air pollution from industrial sources is a continuing concern, especially near residential areas, where public health can be affected. Dispersion of plumes released from stacks depends on wind speed, plume emission rate, stack height, and other meteorological and stack variables. Plume rise is an important aspect of plume dispersion because it increases the apparent release height, which leads to lower ground-level concentrations. Plume rise models are therefore important components of air dispersion models. Plume rise linked with flare combustion has received only minimal attention in the scientific literature to date, despite its importance. This thesis develops a numerical model of plume rise with flare combustion based on material, heat, mass, and momentum balances. The basis of the model was proposed by Scire et al. (2000)as Plume Rise Model Enhancements (PRIME) for plume rise and building downwash. Later on, De Visscher (2009) extended the PRIME model to account for flare combustion by keeping track of the amount of oxygen mixed into the plume. The current study is an extension of the work of De Visscher (2009) to account for the rate of reaction. The proposed model considers the reaction kinetics to produce more realistic and accurate results. Moreover, emissivity, which plays an important role in the heat conservation equations but which was only parameterized in the original model, is calculated explicitly to increase the accuracy of the model. In the first step, a set of heat, material, and momentum conservation equations are proposed related to the wind speed and the stack parameters. The basic model is obtained by solving these equations simultaneously assuming instantaneous combustion. Then the kinetics of combustion to CO and CO2 were considered as a model extension. The emissivity calculation was also enhanced to obtain more accurate results in the improved model. Finally, the air dispersion model CALPUFF was run according to the proposed flare model and a simpler and less realistic flare model by Beychok (2005) to compare results of the models. This new flare method is simple enough to be embedded into the air dispersion modeling software (such as CALPUFF). Currently, regulatory models use variants of Beychok’s (2005) approach, but these are not realistic. More sophisticated models exist (e.g. based on CFD), but these are too complex to be used in combination with air dispersion models. Thus, this study offers a simple and reliable flare model to be used in air dispersion models.

description: We analyze the optical properties of one-dimensional (1D) PT-symmetric structures of arbitrary complexity. These structures violate normal unitarity (photon flux conservation) but are shown to satisfy generalized unitarity relations, which relate the elements of the scattering matrix and lead to a conservation relation in terms of the transmittance and (left and right) reflectances. One implication of this relation is that there exist anisotropic transmission resonances in PT-symmetric systems, frequencies at which there is unit transmission and zero reflection, but only for waves incident from a single side. The spatial profile of these transmission resonances is symmetric, and they can occur even at PT-symmetry breaking points. The general conservation relations can be utilized as an experimental signature of the presence of PT-symmetry and of PT-symmetry breaking transitions. The uniqueness of PT-symmetry breaking transitions of the scattering matrix is briefly discussed by comparing to the corresponding non-Hermitian Hamiltonians.

description: The extremely fast cooling rate of selective laser melting can significantly refine the lamellar structure of eutectic high-entropy alloys. However, extreme solidification conditions also promote the appearance of honeycomb-like cellular structures. Here, we show that the competitive growth of the primary phase and eutectic determines the formation of cellular structure. Our results demonstrated that the composition conditions of FCC-B2 eutectic formation are more severe at excessively high growth rates. Therefore, although increasing the cooling rate will significantly decrease the size of the cellular structure, it cannot change the morphology of the cellular structure of Ni32.5Co15Cr10Fe23Al17.5Mo1.5W0.5 hypereutectic alloy. Based on the competitive growth of the primary phase and eutectic, this work reveals the inner mechanism of cellular structure formation at excessive cooling rates for the first time.
