An Elastic Half Space with a Moving Punch
Authors: Saha Sandip , Kumar Vikash , Narayan Das Apurba
Published: November 2021

The dynamic problem of a punch with rounded tips moving in an elastic half-space in a fixed direction has been considered. The static problem of determining stress component under the contact region of a punch has also been solved. Fourier integral transform has been employed to reduce the problems in solving dual integral equations. These integral equations have been solved using Cooke’s [1] result (1970) to obtain the stress component. Finally, exact expressions for stress components under the punch and the normal displacement component in the region outside the punch have been derived. Numerical results for stress intensity factor at the punch end and torque applied over the contact region have been presented in the form of graph.

Published: November 2021

The endogenous mu-opioid receptor (MOR) system modulates a multitude of social and reward-related functions, and exogenous opiates also influence sex drive in humans and animals. Sex drive shows substantial variation across humans, and it is possible that individual differences in MOR availability underlie interindividual of variation in human sex drive. We measured healthy male subjects’ (n = 52) brain’s MOR availability with positron emission tomography (PET) using an agonist radioligand, [11C]carfentanil, that has high affinity for MORs. Sex drive was measured using self-reports of engaging in sexual behaviour (sex with partner and masturbating). Bayesian hierarchical regression analysis revealed that sex drive was positively associated with MOR availability in cortical and subcortical areas, notably in caudate nucleus, hippocampus, and cingulate cortices. These results were replicated in full-volume GLM analysis. These widespread effects are in line with high spatial autocorrelation in MOR expression in human brain. Complementary voxel-based morphometry analysis (n = 108) of anatomical MR images provided limited evidence for positive association between sex drive and cortical density in the midcingulate cortex. We conclude that endogenous MOR tone is associated with individual differences in sex drive in human males.

Authors: Holiuk Ye.L. , Kabatsii M.S. , Filipchuk V.V. , Melnyk M.V. , Lukianova N.Yu.
Published: November 2021

Summary. Slipped capital femoral epiphysis (SCFE) is a multifactorial disease caused by a number of factors, and each of them can be triggered in its occurrence. Modern research is increasingly pointing to the leading role of epigenetic structures in the origin and course of this group of diseases. In recent years, the most promising area is the study of the role of microRNAs as an epigenetic factor that plays a leading role in the pathogenesis of multifactorial diseases.

Objective: to develop a methodology for genetic genealogical examination of patients with juvenile epiphysiolysis of the femoral head.

Materials and Methods. The study material was 26 patients with SCFE (15 girls and 11 boys) in different periods of sexual development: prepuberty – 7 patients, induction of puberty – 12 patients, and puberty and postpuberty – 7 patients. A questionnaire developed by us was used for clinical and genealogical research of the patients. The material for the epigenetic study, namely the study of microRNA-21 expression in patients with SCFE, was venous blood.

Results. The expression of microRNA-21 in the blood of patients with SCFE is different (average expression is 0.86 conventional units) from those of healthy donors (average 0.393 conventional units) of the same age (p<0.05). Analysis of dependence on the period of sexual development revealed statistical differences in indicators depending on the group (p<0.05). No dependence of the level of microRNA-21 expression in patients with SCFE on sex and the period before or after surgery (p>0.05) was revealed. The obtained data on the probability of the influence of hereditary factors on the occurrence of SCFE are statistically significant (p<0.05).

Conclusions. Our results of epigenetic and clinical genealogical research of patients with SCFE showed a high probability of influence of hereditary and epigenetic factors on the occurrence and course of this disease.

Published: November 2021

Biogenic nanoparticles (NPs) derived from microbes present an excellent opportunity to deal with various challenges in medicine, diagnosis, environment and agriculture. In the area of agriculture sciences, researchers are facing challenges related to excessive utilization of pesticides which can be answered by utilizing plant growth-promoting (PGP) microbes. Herein, we have employed the culture filtrate of two PBP bacteria strains, Serratia marcescens and Burkholderia cepacia to prepare biogenic silver NPs. The biogenic silver NPs were characterized by various techniques viz. UV-VIS spectroscopy, SEM, XRD and FTIR. The biogenic AgNPs were able to control the growth of phytopathogenic fungi Aspergillus niger, A. fumigatus, Fusarium oxysporum, Pythium sp., and Rosellinia sp. by more than 80% as examined by in vitro growth reduction on agar medium. Very significantly, the growth inhibition of seedlings by phytopathogenic fungi was efficiently rescued using biogenic AgNPs derived from PGP bacteria. These results indicate the potential use of biogenic NPs to reduce the burden of chemical-based pesticides.
Computational prediction of electrical and thermal properties of graphene and BaTiO3 reinforced epoxy nanocomposites
Authors: Kumar Mishra Raghvendra , Goel Saurav , Yazdani Nezhad Hamed
Published: November 2021

Graphene based materials e.g., graphene oxide (GO), reduced graphene oxide (RGO) and graphene nano platelets (GNP) as well as Barium titanate (BaTiO3) are emerging reinforcing agents which upon mixing with epoxy provides composite materials with superior mechanical, electrical and thermal properties as well as shielding against electromagnetic (EM) radiations. Inclusion of the aforementioned reinforcing agents has shown to improve the performance, however, the extent of improvement has remained uncertain. In this study, a computational modelling approach was adopted using COMSOL Multiphysics software in conjunction with Bayesian statistical analysis to investigate the effects of including various filler materials e.g. GO, RGO, GNP and BaTiO3 in influencing the direct current (DC) conductivity (σ), dielectric constant (ε) and thermal properties on the resulting epoxy polymer matrix composites. The simulation of epoxy composites were performed for different volume percentage of the filler materials by varying the geometry of the filler material. It was observed that the content of GO, RGO, GNPs and the thickness of graphene nanoplatelets can alter the DC conductivity, dielectric constant, and thermal properties of the epoxy matrix. The lower thickness of GNPs was found to offer the larger value of DC conductivity, thermal conductivity and thermal diffusivity than rest of the graphene nanocomposites, while, the RGO showed better dielectric constant value than neat epoxy, and GO, GNP nanocomposites. Similarly, BaTiO3 nanoparticles content and diameter were observed to alter the dielectric constant, DC conductivity and thermal properties of modified epoxy in several order magnitude than neat epoxy. In this way, the higher diameter particles of BaTiO3 showed better DC conductivity properties, dielectric constant value, thermal conductivity and thermal diffusivity. Moreover, this research provides guidance for further computational examination on the selection of GNP and BaTiO3 materials for the enhancement of the electrical and thermal properties of the epoxy matrix.

Authors: Stetsenko S. , Tsyfra T. , Vahovich I. , Sichnyi S. , Оleksandr L.
Published: November 2021

The article deals with features and principles of the price monitoring system for material and technical resources operating now in the road industry. To improve the process of information collection, processing, and analysis concerning the cost of building materials, products, and structures, as well as other types of resources, it is proposed to reinforce a centralized single database of material and technical resources on the basis of regional data. Minimization of costs for data collection, storage, processing and use is possible only with the maximum automation of electronic data collection and exchange, which is realized during the implementation of elements of the centralized monitoring system (CMS) in practice. The architecture, algorithm, and regulations for the formation of a CMS are proposed.

Authors: Grassi Freire Lucas
Published: November 2021

Este ensaio expõe e discute o princípio normativo da soberania das esferas sociais, tomando, por base, a formulação original do princípio conforme articulada pelo estadista e teólogo Abraham Kuyper (1837-1920). Em seguida, trata do problema da tensa relação entre a esfera do governo civil e as demais, principalmente na teoria auxiliar que legitima em alguns casos a intervenção do governo civil em relação a outras esferas. O argumento é ilustrado ao longo do ensaio com exemplos sobre a relação entre as esferas do governo civil, da igreja e da educação, embora outras possíveis aplicações sejam também mencionadas. O ensaio termina com uma avaliação crítica da teoria auxiliar do intervencionismo do governo civil, indicando as dificuldades apresentadas no contexto da crise do espaço público atual e do pluralismo de princípios.
A Subsidiariedade no Estado Nacional Moderno
Authors: Pedrosa Daltro Santos Gustavo Adolfo
Published: November 2021

O artigo procura delinear a profundidade e o alcance do princípio da subsidia-riedade, um dos princípios básicos e estruturantes da Doutrina Social da Igreja Católica. Para melhor entender o alcance e a aplicação da subsidiariedade, é apresentada uma interpretação do processo de constituição do Estado nacional moderno com ênfase na crescente concentração de poder e autoridade social no Estado, em detrimento das redes de solidariedade social pré-modernas. Em seguida, os pronunciamentos e documentos papais que articularam o princípio são analisados para abstrair as dimensões mais significativas da subsidiariedade, do ponto de vista da ética social, da antropologia filosófica e da teologia.

While social values are values held by society, regarding what is considered good and what is considered bad by society.Keywords: Social Values, Spiritual Values, Islamic Boarding School
INFLUENCE OF APARTMENTS’ MODERNIZATION ON THE TEMPERATURES OF HEATING SYSTEM IN THE BUILDING
Authors: Šiupšinskas Giedrius , Bielskus Juozas , Rogoža Artur
Published: November 2021

When modernizing apartment buildings, heating appliances are replaced or old ones are left, high thermal temperatures are usually maintained, thus limiting the increase in the DH system’s efficiency. In the article, in order to evaluate the impact of the reduced thermal temperature of the building on space heating when the radiator area remains constant, 3 alternatives have been analyzed. They include cases when after the building modernization old heating appliances are left, but the temperature of the heat carrier is reduced up to 60/40/20 °C in one case or even up to 45/25/20 in another alternative. There has also been examined the possibility of reducing the heat carrier temperature of the heating system without modernization of the building. An hourly data analysis of the heating system model for two typical months of the heating season has been performed. The analysis shows that after the modernization of the building, when heating device areas are left the same, the existing heating temperature can be reduced to 60/40/2020 °C.
Low-luminosity Galaxies in the Early Universe Have Observed Sizes Similar to Star Cluster Complexes

Published: November 2021

We compare the sizes and luminosities of faint z = 6–8 galaxies magnified by the Hubble Frontier Fields clusters with star-forming regions, as well as more evolved objects, in the nearby universe. Our high-redshift comparison sample includes 330 z = 6–8 galaxies, for which size measurements were made as part of a companion study where lensing magnifications were estimated from various public models. Accurate size measurements for these sources are complicated by the lens model uncertainties, but other results and arguments suggest that faint galaxies are small, as discussed in a companion study. The measured sizes for sources in our comparison sample range from <50 pc to ∼500 pc. For many of the lowest-luminosity sources, extremely small sizes are inferred, reaching individual sizes as small as 10–30 pc, with several sources in the 10–15 pc range with our conservative magnification limits. The sizes and luminosities are similar to those of single star cluster complexes like 30 Doradus in the lower-redshift universe and—in a few cases—super star clusters. The identification of these compact, faint star-forming sources in the z ∼ 6–8 universe also allows us to set upper limits on the proto-globular cluster luminosity function at z ∼ 6. By comparisons of the counts and sizes with recent models, we rule out (with some caveats) proto-globular cluster formation scenarios favoring substantial (ξ = 10) post-formation mass loss and set useful upper limits on others. Our size results suggest we may be very close to discovering a bona fide population of forming globular clusters at high redshift.

We describe a process for cross-calibrating the effective areas of X-ray telescopes that observe common targets. The targets are not assumed to be “standard candles” in the classic sense, in that we assume that the source fluxes have well-defined, but a priori unknown values. Using a technique developed by Chen et al. that involves a statistical method called shrinkage estimation, we determine effective area correction factors for each instrument that bring estimated fluxes into the best agreement, consistent with prior knowledge of their effective areas. We expand the technique to allow unique priors on systematic uncertainties in effective areas for each X-ray astronomy instrument and to allow correlations between effective areas in different energy bands. We demonstrate the method with several data sets from various X-ray telescopes.

One way the active galactic nuclei (AGN) are expected to influence the evolution of their host galaxies is by removing metal content via outflows. In this article we present results that show that AGN can have an effect on the chemical enrichment of their host galaxies using the fossil record technique on CALIFA galaxies. We classified the chemical enrichment histories of all galaxies in our sample regarding whether they show a drop in the value of their metallicity. We find that galaxies currently hosting an AGN are more likely to show this drop in their metal content compared to the quiescent sample. Once we separate the sample by their star-forming status we find that star-forming galaxies are less likely to have a drop in metallicity but have deeper decreases when these appear. This behavior could be evidence for the influence of either pristine gas inflows or galactic outflows triggered by starbursts, both of which can produce a drop in metallicity.

Published: November 2021

The Dingqu River Basin, a major tributary of the upper Yangtze River, is located at southeast edge of the Qinghai-Tibet Plateau of China. The fishes of this plateau constitute a major faunal component of this basin, particularly Schizothoracinae (Cypriniformes: Cyprinidae) and Triplophysa (Cypriniformes: Nemacheilidae). Hydropower development is an impact that affects natural habitats and biological resources of the upper Yangtze River and this has led to a decrease in biodiversity. This study investigated the species diversity of fishes of the Dingqu River Basin and accumulated basic data for conservation of biodiversity and assessment of ecological health of the upper Yangtze River.

The upper streams of the Jinshajiang River harbours numerous endemic fish species in China. Most of them belong to the Qianghai-Tibet Plateau fish fauna. However, while the fish species of the Jinshajiang River have been well studied, there is still a gap in the research on fish species diversity of the Dingqu River Basin tributary. This study provides information for 18 native fish species belonging to two orders, four families, three subfamilies and eight genera, and is the first complete record of fishes in the Dingqu River Basin, a primary tributary of the Yangtze River. Supplemental information of species diversity in the Jinshajiang River is also provided. The study includes two datasets, which present taxonomic, distribution, habitat condition, endemism and threat information for each species collected from the Dingqu River Basin and historical literature, respectively. In particular, these fish species all have limited distribution within the south-eastern Qinghai-Tibet Plateau areas of China and could determine the importance of habitat protection for the upper Yangtze River.

La réinterprétation des frontières nationales est mobilisée pour produire des « vins politiques » de manière calculée afin de s’assurer que ceux-ci épousent un marché de consommateurs susceptibles de réagir à une telle politisation de leur breuvage.
Itinéraires de Chinois dans les vignobles du bordelais ou le renversement de la figure de « l’étranger »
Authors: Crenn Chantal
Published: November 2021

Cet article s’interroge sur les liens qui se tissent quotidiennement entre salariés français et investisseurs chinois·e·s dans un territoire situé à la marge du bordelais. Il dévoile comment les marques de l’autochtonie et de l’étrangeté, fruits d’échanges économiques et symboliques, se trouvent transformées au sein d’une des communautés viticoles bordelaises appauvries. Cette communauté se saisit – pour certains de ses membres – de cette présence étrangère inattendue pour (re)donner de la valeur marchande et symbolique à son vin tout en redoutant que les investisseurs chinois aient définitivement la main mise sur un fleuron de l’économie française et/ou pire disparaissent sans laisser de trace.
De la production à la consommation : le statut ambigu du vin à Ramallah
Authors: Gasparotto Mariangela
Published: November 2021

Si la consommation du vin ne concerne qu’une partie des habitants des Territoires palestiniens, sa production s’est développée dans certaines régions tout au long de l’histoire. Plurielles, les dynamiques qui tournent autour du vin sont fortement liées à la situation de colonisation ainsi qu’aux normes sociales et religieuses qui régissent ces territoires sous occupation. À travers une analyse des lieux de la consommation, de la production de vin et des interdits qui touchent cette boisson, il s’agira de discuter du statut ambigu du vin à Ramallah. L’analyse situationnelle montrera la porosité des normes sociales et religieuses, les différents modes de concevoir l’engagement politique ainsi que la diversité des tactiques mises en œuvre par les habitants afin de les contourner.

C’est à cette part de notre collègue et ami disparu qu’est consacré cet article. Ses travaux sur Django Reinhardt, le livre Jazz et anthropologie qu’il publia avec Jean Jamin en 2001 et le séminaire du même titre que les deux compères créèrent et animèrent à l’EHESS de 2001 à 2009 imposèrent le jazz comme objet anthropologique au sens plein et firent de cette décennie une période d’intense effervescence jazzologique.
Rhapsody in Dark

Il est des œuvres de fiction qui peuvent transformer les mentalités. C’est le cas, par exemple, des Hauts de Hurle-Vent d’Emily Brontë, où apparaît une autre vision des Gypsies auxquels se rattache l’un des personnages principaux. Ces œuvres peuvent également avoir une portée ethnologique non pas au sens où, à l’image de romans naturalistes, elles offriraient des documents sur les rapports sociaux, mais au sens où elles permettraient d’opérer une variation imaginaire de ceux-ci qui prendraient alors une signification neuve. C’est le cas de L’Homme foudroyé de Blaise Cendrars qui a été l’un des écrivains de prédilection de Patrick Williams, et dont les quatre Rhapsodies gitanes du livre lui permettent de s’interroger sur ce qu’il appelle l’illusion autobiographique, qui peut être aussi une illusion ethnographique.
Random attractors for dissipative systems with rough noises
Authors: Duc Luu Hoang
Published: November 2021

We provide an analytic approach to study the asymptotic dynamics of rough differential equations, with the driving noises of Hölder continuity. Such systems can be solved with Lyons' theory of rough paths, in particular the rough integrals are understood in the Gubinelli sense for controlled rough paths. Using the framework of random dynamical systems and random attractors, we prove the existence and upper semi-continuity of the global pullback attractor for dissipative systems perturbed by bounded noises. Moreover, if the unperturbed system is strictly dissipative then the random attractor is a singleton for sufficiently small noise intensity.
Existence of minimizers for one-dimensional vectorial non-semicontinuous functionals with second order lagrangian
Authors: Zagatti Sandro
Published: November 2021

We study the minimum problem for functionals of the form

   \begin{document}$ \begin{equation} \mathcal{F}(u) = \int_{I} f(x, u(x), u^ \prime(x), u^ {\prime\prime}(x))\,dx, \end{equation} $\end{document}

where the integrand \begin{document}$ f:I\times \mathbb{R}^m\times \mathbb{R}^m\times \mathbb{R}^m \to \mathbb{R} $\end{document} is not convex in the last variable. We provide an existence result assuming that the lower convex envelope \begin{document}$ \overline{f} = \overline{f}(x,p,q,\xi) $\end{document} of \begin{document}$ f $\end{document} with respect to \begin{document}$ \xi $\end{document} is regular and enjoys a special dependence with respect to the i-th single components \begin{document}$ p_i, q_i, \xi_i $\end{document} of the vector variables \begin{document}$ p,q,\xi $\end{document}. More precisely, we assume that it is monotone in \begin{document}$ p_i $\end{document} and that it satisfies suitable affinity properties with respect to \begin{document}$ \xi_i $\end{document} on the set \begin{document}$ \{f> \overline{f}\} $\end{document} and with respect to \begin{document}$ q_i $\end{document} on the whole domain. We adopt refined versions of the integro-extremality method, extending analogous results already obtained for functionals with first order lagrangians. In addition we show that our hypotheses are nearly optimal, providing in such a way an almost necessary and sufficient condition for the solvability of this class of variational problems.
Cesàro summability and Lebesgue points of higher dimensional Fourier series
Authors: Weisz Ferenc
Published: November 2021

We give four generalizations of the classical Lebesgue's theorem to multi-dimensional functions and Fourier series. We introduce four new concepts of Lebesgue points, the corresponding Hardy-Littlewood type maximal functions and show that almost every point is a Lebesgue point. For four different types of summability and convergences investigated in the literature, we prove that the Cesàro means \begin{document}$ \sigma_n^{\alpha}f $\end{document} of the Fourier series of a multi-dimensional function converge to \begin{document}$ f $\end{document} at each Lebesgue point as \begin{document}$ n\to \infty $\end{document}.

Last cholera epidemic has been recorded in Bangladesh between 1992–1993, while few sporadic localized outbreaks have been reported as recent as 2005. Serotype O1 of Vibrio cholera is considered as the principal causative agent which transmits through contaminated drinking water resulting that epidemic. Therefore, the objective of this research was to isolate V. cholera in 3 different water sources; River, pond and tube-well, in 5 different locations of Gazipur, Bangladesh, and to analyze their antibiogram study. A total of 45 water samples were randomly collected for the isolation and identification of Vibrio spp. Samples are then serially diluted in alkaline peptone water and streak on Thiosulfate Citrate Bile Salt Sucrose-TCBS agar for quantification of V. spp. For V. cholera isolation water samples were first enriched in nutrient broth at 37 °C for 16 hours followed by cultivation in selective media; TCBS agar at 37 °C for 24 hours. Yellow colonies on TCBS agar were screed as V. cholera and was confirmed by analyzing their biochemical characteristics like Catalase, Oxidase, MR, VP, Indole, Sugar fermentation. Following isolation antibiotic sensitivity test was performed on each V. cholera isolates to determine their antibiotic sensitivity profile. The results showed, out of 45 samples 12 contained V. cholera. Tube-well water has significantly lower concentration (log CFU/mL) of V. spp. than river and pond water (P < 0.05). Bacterial concentration doesn't deviate (P > 0.05) significantly in 5 different location the sample was collected from. All the 12 isolates were sensitive to Gentamicin and ciprofloxacin (100%), while Chloramphenicol (91.67%), Sulfamethoxazole (91.67%), Azithromycin (66.67%) showed high sensitivity. Isolates showed marginal sensitivity towards Tetracycline (33.33%), and Cephalexin (16.67%) and 100% resistance against antibiotics like Vancomycin, Penicillin, Erythromycin, and Nalidixic Acid. Based on these data we recommend using tube-well water instead of river and pond water for drinking purposes. Furthermore, we suggest selective use of sensitive antimicrobials listed here for therapeutics of cholera outbreak.
Memórias docentes no campo: mapeando professoralidades na roça
Authors: Dos Santos Eliziane Santana , Freixo Alessandra Alexandre
Published: November 2021

Este artigo é fruto de uma pesquisa cartográfica que partiu de uma memória escolar vivenciada no ensino fundamental como potência para reflexões em torno da noção de experiência em Jorge Larrosa e de devir em Gilles Deleuze, em diálogo com Marcos Vilela Pereira e sua noção de professoralidade. O objetivo desta pesquisa consiste em acompanhar os processos de produção de memórias docentes, que visem expressar professoralidades no campo. A pesquisa aconteceu em parceria com duas professoras de uma escola localizada em uma comunidade rural no município de Feira de Santana. O processo de produção de dados se deu utilizando como dispositivos as entrevistas narrativas. As conversas foram associadas à produção de mapas, nos quais se percebem os atravessamentos do espaço escolar na produção de diferenças nas professoras. Construímos elementos de (trans)formação que se tornaram coletivos e nos permitiram refletir sobre outras possibilidades de estar sendo professoras no campo.
Life and Flaking Failure of 13Cr-2Ni-2Mo and SUS440C Stainless Steel Bearings in Water
Authors: Matsubayashi Soji , Fukuda Masato , Kida Katsuyuki
Published: November 2021

The rolling contact fatigue (RCF) tests of 13Cr-2Ni-2Mo and SUS440C stainless steels were carried out in water. Their groove surfaces and the flaking failures were observed. Some hair cracks, wear and high roughness area were found. While the flaking depth of SUS440C was shallower than that of 13Cr-2Ni-2Mo stainless steel, the RCF life of the latter was longer than the former one. The flaking depth did not influence the RCF life.
Experimental and Numerical Examination on Formability and Microstructure of AA3003-H18 Alloy in Single Point Incremental Forming Process

The single-point incremental forming process has witnessed significant advantages in automobiles, aerospace, and medical applications in recent years because of its flexibility in manufacturing complex shapes. In detail, the components are produced only using the toolpath, which is guided by computer-aided manufacturing software. However, during the forming process, the parts might experience fractures, which could heavily impact the formed part's geometric accuracy. The main purpose of this study is to analyze the formability of an AA3003-H18 aluminum alloy material in the SPIF process; for this purpose, the material properties are extracted from the experimental simple tensile test in three directions corresponding to the material rolling direction. At first, a simple tensile test is modeled and estimated the material properties for conducting the numerical simulations. Second, the real-time experiments of the SPIF process in terms of predefined forming conditions are performed, and then the surface roughness was measured to check the surface quality of the formed parts. Then, the formed parts are scanned using a 3D ATOS scanner and compared against the desired computer-aided design (CAD) model. Eventually, the numerical results are discussed in comparison with the experimental outcome and displayed a significant correlation toward the expected results. This results comparison communicates that the introduced finite element (FE) model can be adopted for investigating the appearance of thinning location, thinning reduction, distributions of stress and strain. The overall results show that satisfying material formability in better surface finish and geometric dimensional accuracy can be accomplished when the forming conditions are designed appropriately.
Effect of Cold Rolling on the Microstructure and Mechanical Behaviors of High-Nitrogen and Low-Nickel Alloy
Authors: Yang You , Li Hong Shuai , Huang Yu Xin
Published: November 2021

The effects of different cold rolling deformations on the microstructure and mechanical properties of high nitrogen and low nickel alloys were investigated. The microstructure of high nitrogen alloys with different rolling deformations were characterized by EBSD and TEM. The tensile mechanical properties of the high nitrogen alloys at room temperature were tested. The results showed that the microstructure of the cold rolled high nitrogen alloy with deformation of 0% to 70% shows a twinning process. The twin thickness of the high nitrogen alloy without deformation is micron degree. When the rolling deformation is over 50%, the average thickness of the deformation twin is 23nm. When the rolling deformation increases to 70%, the average thickness of the twin is 14nm. When the rolling deformation increases from 0% to 70%, the cold rolled high nitrogen alloy exhibits high strength (1001-2236 MPa) and excellent plasticity (5.9%-64.1%). It is beneficial to have a good combination of strength and plasticity after rolling deformation.
