摘要：

A physically based model is employed to trace the strain-hardening behavior of a metastable medium-entropy alloy (MEA) Fe-61(CoNi)(29)Cr-10 governed by a deformation-induced martensitic transformation. The approach is based on calculating the local quantities of the individual phases by means of constitutive modeling. An acceptable agreement between the experimental and the calculated stress-strain curves is verified. The model also demonstrates the variation of the phase composition of the MEA with strain due to the phase transformation.
