Lattice distortion and magnetic property of high entropy alloys at low temperatures
文献摘要：
Deformation mechanisms and magnetic properties of medium and high entropy alloys(MEA/HEAs)closely relate to lattice distortion and are strongly temperature-dependent,in particular,at low temper-ature ranges.However,little attention has been paid to the evolution of lattice distortion with tempera-ture decreasing and its effects on deformation behavior and magnetic state transition.In this work,we carry out in situ synchrotron radiation based X-ray powder diffraction(SR-XRD)experiments from 293 to 123 K aiming for determining lattice distortion evolutions of CrCoNi MEA,CrFeCoNi and CrMnFeCoNi HEAs.Magnetic measurements at corresponding low temperatures and cryogenic ranges are further con-ducted.The in situ SR-XRD results demonstrate a general reduction of lattice distortion magnitude with temperature decreasing,which shows a similar tendency with that of reported stacking fault energy(SFE)values.It is thus suggested that lattice distortion reduction possibly makes a critical contribution to defor-mation mechanism transition.The magnetic measurement results show a clear ferromagnetic transition of CrFeCoNi HEA when temperature is below 173 K.While,no obvious magnetic state transition is ob-served for CrCoNi MEA and CrMnFeCoNi HEA.The present findings on lattice distortion evolutions will pave the way for designing targeted HEAs with particular properties.
