Theoretical and experimental study of phase transformation and twinning behavior in metastable high-entropy alloys

Combined theoretical and experimental efforts are put forward to study the critical factors influencing deformation mode transitions in face-centered cubic materials. We revisit the empirical relationship between the stacking fault energy (SFE) and the prevalent deformation mechanism. With ab initio calculated SFE, we establish the critical boundaries between various deformation modes in the model Cr-Co-Ni solid solution alloys. Satisfying...
