Stacking faults are often found in fcc alloys with low stacking fault energy and have been known to play an important role in both plastic deformation and phase transformations, particularly the fcc{yields}hcp martensitic transformation. In 1975, Brook et al. reported that the extending and contracting of stacking faults might be one of the mechanisms of the shape memory effect. However, no detailed explanation was given. The present work is a detailed analysis of the behavior of stacking faults under an applied stress and discussion of its relation to pseudoelasticity, the shape memory effect and the fcc{yields}hcp martensitic transformation.
