Abstract

The combined increase in strength and ductility observed in high-entropy alloys broadens the palette of advanced materials. Understanding their behavior on a fundamental level facilitates the optimization of their mechanical characteristics. The atomistic theoretical approach presented herein discusses the Al-driven $B2$-type magnetochemical transition in Fe-Cr-Co-Ni-Al alloys. Diversity in the mechanical behaviors of the partially ordered and disordered phases affords opportunities to design specific properties by controlling the level of ordering in multiphase high-entropy alloys, to promote the engineering of strong, durable, and lightweight machines.
