TLDR
In this paper, an AlCrCuNiFeCo high entropy alloy was processed and its high temperature deformation behavior was examined as a function of temperature (700-1030 degrees C) and strain rate (10(-3)-10(-1) s(-1)), so as to identify the optimum thermo-mechanical processing (TMP) conditions for hot working of this alloy.About:

TL;DR: In this paper, a constitutive equation was formulated for describing interdependency between deformation temperature, strain rate, flow stress and strain, and the estimated apparent activation energy (Q) ∼350 kJmol-1 for the hot deformation was approximately similar to the activation energy for diffusion of the slowest diffusing element Ni in this alloy.
