Lattice Distortion Promotes Incipient Plasticity in Multiprincipal Element Alloys

Luling Wang,
Yang Cao,
Yonghao Zhao

Abstract: Multiprincipal element alloys usually exhibit earlier pop-in events than pure metals and dilute solid solutions during nanoindentation experiments. To understand the origin of this phenomenon, large-scale atomic simulations of nanoindentation were performed on a series of metallic materials to investigate the underlying physics of incipient plasticity at the nanoscale. Statistical result shows that lattice distortion δ and normalized critical pressure p c /E s follow a power-law relationship. Via quantitative … Show more
