Authors: Smith David , Pickett Paula , Grabowski Theresa , Thorpe Joncy , Azarmi Fardad 
Published: August 2024

Abstract
Cobalt chromium (CoCr), a well-known biocompatible material, was additively manufactured using direct energy deposition (DED) technology in this study. Since DED is a relatively new addition to additive manufacturing (AM) processes, there is not enough information about important properties of fabricated parts and components using this technology. This study investigates some important mechanical characteristics of the additively manufactured CoCr using a variety of numerical simulation methods in addition to mechanical tests and experiments. Mechanical experiments such as hardness, wear, and flexural bending test were conducted on DED processed samples. All experiments were also conducted on conventionally processed CoCr specimens for comparison purposes. This study attempts to explain mechanical properties in terms of microstructural characteristics of each sample. DED processed CoCr samples exhibited a complex microstructure with a variety of features such as cellular, columnar, and equiaxed grains within their melt pools. While the DED processed sample had a lower hardness compared to the conventionally processed one, it exhibited a higher wear resistance. These results were discussed in terms of microstructural characteristics and metallurgical bonding knowing that porosity level was negligible in both samples. The out-of-plane mechanical strength of CoCr samples was measured by conducting flexural bending test, and the conventional sample showed a higher flexural modulus than the DED sample. The bend tests were also numerically simulated using two different finite element analysis (FEA) procedures. The FEA results for the DED and conventionally processed samples follow the same trend as the results obtained from the experimental flexural bending test. The layer structure and interfacial bonding of the DED sample could have contributed to the lower flexural modulus compared to the conventional sample.

Abstract
Cold spray is a solid-state metal powder deposition technique that has proven to be highly effective in depositing a wide range of metals, including aluminum and its alloys. However, higher strength, heat treatable Al alloys appear to exhibit variable deposition efficiencies and responses to heat treatments designed to increase ductility. This work is aimed at understanding the sources of these variabilities. In this study, 6061 (0.9% Mg, 0.6% Si, 0.3% Cu, 0.1% Cr, 0.1% Fe) alloy is compared to 7075 (6% Zn, 1.6% Cu, 2.4% Mg, 0.2% Cr, 0.3% Fe) alloy. These are common heat treatable alloys, but they exhibit quite different cold spray characteristics. Generally, 7075 is more problematic in terms of deposition efficiency and the mechanical properties after heat treatment. The alloys were processed under various cold spray conditions, including laser assisted cold spray designed to soften the 7075, and subjected to heat treatments intended to increase ductility. The microstructure and mechanical properties of the as sprayed and heat-treated coatings were characterized and compared. The results of this investigation will reveal possible mechanisms explaining the different cold spray behaviors and some suggestions will be proposed to overcome the problems associated with 7075.

Abstract
Cold spray is an emergent sold-state manufacturing process based on high-speed consecutive collision of small sized particles powders. Such a cold process principle led to the recent development of coatings for various surface functionalization and direct component manufacturing applications. This study investigates the mechanisms of porosity formation during the additive growth of Al1050 powders. To this end, a thermo-mechanical computational model based on the Eulerian computational approach using the Johnson-Cook constitutive law is applied on the case of an additive growth from a stacking of powder layers. The model uses in-flight velocities measured by a DPV2000 system during a cold spray test and an isentropic gas flow model. The measurements show the velocity distribution within the powder jet at the nozzle exit and consists of a Gaussian-like distribution within the typical range of 450-650m/s. The centerline zone at the nozzle exhibits the highest velocity. These data used as input data of the model allowed to apprehend some circumstances of pore formation, in terms of site occurrence, pore behavior over time, and deficient in-flight velocity.

BACKGROUND: Numerous studies have shown that m6A plays an important regulatory role in the development of tumors. HNRNPA2B1, one of the m6A RNA methylation reading proteins, has been proven to be elevated in human cancers. OBJECTIVE: In this study, we aimed to identify the role of HNRNPA2B1 in breast cancer. METHODS: HNRNPA2B1 expression was investigated via RT-qPCR and TCGA database in breast cancer. Then, the function of HNRNPA2B1 on cancer cell was measured by CCK8 assays, colony formation and scratch assays. In addition, HNRNPA2B1 expression in BRCA was explored via the Wilcoxon signed-rank test, KruskalWallis test and logistic regression. The association with HNRNPA2B1 expression and survival were considered by KaplanMeier and Cox regression analyses. The biological function of HNRNPA2B1 was analyzed via gene set enrichment analysis (GSEA) and the cluster Profiler R software package. RESULTS: We found that HNRNPA2B1 was highly expressed and induced cell proliferation and migration in breast cancer. Moreover, we observed HNRNPA2B1 induced tumor growth in vivo. In addition, we also found HNRNPA2B1 expression was associated with characteristics and prognosis in breast cancer patients. CONCLUSION: Our findings suggested that HNRNPA2B1 promoted tumor growth and could function as a new potential molecular marker in breast cancer.
