Deformation mechanisms in high entropy alloys: a minireview of short-range order effects

Abstract

The complex atomic scale structure of high entropy alloys presents new opportunities to expand the deformation theories of mechanical metallurgy. In this regard, solute-defect interactions have emerged as critical piece...

Unveiling the mechanism of tuning elemental distribution in high entropy alloys and its effect on thermal stability

“…Moreover, different degrees of chemical SRO in the nanoscratching process have been examined by hybrid MC/molecular dynamics (MD) simulations, revealing that the SRO-600K sample displayed enhanced resistance to plastic deformation and increased structural stability. 14 As a result, the issue of the chemical SRO effect has attracted growing interest in the past 20 years within the community, 15 e.g. , studies on the thermal stability of local chemical ordering and its impact on the mechanical properties of HEAs.…”
