报告摘要:This study investigates the atomic-scale deformation mechanism of the multiphase CoCrFeNi high-entropy alloys (HEAs) at liquid helium, liquid nitrogen, and room temperatures. The multiphase HEA with a million atoms is prepared by molecular dynamics simulation of melt and quench. An inconsistent evolution of microstructure under tensile deformation is detected by quantitative analysis. Besides, by extracting features from empirical formulas, a machine learning model is presented to predict the fatigue life of multi-principal element alloys.
