This work attempts to understand the in vitro biocompatibility of ultrafine grained titanium prepared by ECAP route. The results obtained from mouse fibroblast cell line 3T3 showed a better adherence and proliferation on specimen compared coarse grain Grade-2 Ti Ti6Al4V alloy. could be attributed increased surface energy boundary possibly presence large number nano-size conical groove-like structures (at triple point junctions boundaries surface)
This work was aimed to produce Cr 2 AlC powder through two‐step reactions and sinter it under a pressureless condition, the related synthesis sintering mechanisms were evaluated. of ∼9 μm in size produced using CrC x Al powders sintered relative density ∼95.5%. The characterized by an activation energy 267±23 kJ/mol mixed mode comprised surface diffusion mechanism transient liquid‐phase caused melting Al–Cr intermetallic impurities. sample exhibited Vickers hardness 3.4 GPa.
Abstract Graphite is an irreplaceable anode for Lithium‐ion batteries (LIBs) at status quo, and its demand will soar amid the supply chain sustainability concerns of natural graphite (NG) synthetic (SG). Herein, LIB‐grade produced using a less energy‐intensive catalytic graphitization process. This work explores (CTG) growth mechanism, impact conditions on degree graphitization, aspects developing high‐rate anodes, upscaling strategies, techno‐economic prospects. Operando thermal X‐ray...
High-entropy alloys (HEAs) have emerged as a new alloy system, with many attractive properties. Among the fabrication routes, mechanical alloying followed by sintering, been widely used. However, sintering mechanisms of HEA powders not yet fully understood. This work attempts to understand kinetics CoCrFeNiMn powders. A comparative study has done on as-milled and annealed conditions, which revealed different behaviours. Decreasing densification rates increasing activation energies were...
Abstract The purpose of this study is to develop an artificial neural network (ANN) model predict and analyze the relationship between properties process parameters polyvinyl chloride (PVC) composites. tensile strength, ductility, density PVC are modeled as a function virgin PVC, recycled CaCO 3 , di‐2‐ethylhexyl phthalate, chlorinated paraffin wax, particle size. ANN trained using backpropagation algorithm. developed was validated with set unseen test data. correlation coefficient adj. R 2...
The present study focused on the development of NiMoAl-based self-lubricating composites using solid lubricants as second phase by powder metallurgy. For this, Cr2AlC MAX phase, Cr2AlC-Ag, and MoS2 powders were mixed with matrix subsequently hot pressed to produce bulk composite samples. average hardness wear resistance found be increased addition MoS2, Cr2AlC-Ag NiMoAl matrix. was more effective in improving than MoS2. has about 75% that alloy. A scanning Kelvin probe system used surface...
