FeNiCrCoCu high-entropy alloy (HEA) is widely used in aerospace, energy, machinery manufacturing and other fields because of its excellent mechanical properties. Studying the effect of temperature on its torsional properties can further improve the torsional properties of FeNiCrCoCu HEA, so as to meet the needs of various applications of this material in industrial production and life. The twisting process of FeNiCrCoCu HEA at different temperatures was studied based on molecular dynamics method. It was found that the deformation resistance of FeNiCrCoCu HEA at low temperature was stronger and the surface lattice distortion was smaller at the end of torsion.

摘要

FeNiCrCoCu high-entropy alloy (HEA) is widely used in aerospace, energy, machinery manufacturing and other fields because of its excellent mechanical properties. Studying the effect of temperature on its torsional properties can further improve the torsional properties of FeNiCrCoCu HEA, so as to meet the needs of various applications of this material in industrial production and life. The twisting process of FeNiCrCoCu HEA at different temperatures was studied based on molecular dynamics method. It was found that the deformation resistance of FeNiCrCoCu HEA at low temperature was stronger and the surface lattice distortion was smaller at the end of torsion.
