| 研究実績の概要 |
In order to clarify the optimized state between the fabrication condition by spark plasma sintering and mechanical properties of the sintered CoCrFeMnNi high entropy alloy, the compressive testing for determining strength and fatigue properties was performed based on a series of sintering conditions. In the simulation, variations in temperature range and pressure level are set by giving parameters within the range selected by prior investigation of experimental works. Microstructural evolution under compressive deformation was also examined. Dislocation and phase analysis were performed by molecular dynamics simulation. This study contributes to understanding the compressive strength and fatigue characteristics based on the sintered state of CoCrFeMnNi high entropy alloy.
