We revisit the meaning of stacking fault energy (SFE) and the assumptions of equilibrium dissociation of lattice dislocations in concentrated alloys. SFE is a unique value in pure metals. However, in ...
Stacking fault tetrahedra (SFTs) are ubiquitous vacancy‐cluster defects in face‐centred cubic (FCC) metals, formed under conditions of plastic deformation, quenching or irradiation. Each SFT comprises ...
