摘      要：Combined theoretical and experimental efforts are put forward to study the critical factors influencing deformation mode transitions in face-centered cubic *** revisit the empirical relationship between the stacking fault energy(SFE)and the prevalent deformation *** ab initio calculated SFE,we establish the critical boundaries between various deformation modes in the model Cr-Co-Ni solid solution *** agreement between theoretical predictions and experimental observations are *** findings shield light on applying quantum mechanical calculations in designing transformation-induced plasticity and twinning-induced plasticity mechanisms for achieving advanced mechanical properties.
