Open AccessThe influence of dilute aluminum and molybdenum on stacking fault and twin formation in FeNiCoCr-based high entropy alloys based on density functional theory
Stacking faults, as defects of disordered crystallographic planes, are one of the most important slip** mechanisms in the commonly seen lattice, face-centered cubic (FCC). Such defects can initiate twinning ...
