The effects of self-accommodation and plastic accommodation in martensitic transformations and the displacement vector for lattice deformation are discussed. The authors propose that the formation of an invariant habit plane is connected with the self-accommodation between different martensitic variants and results in the formation of internal twinned martensites; the plastic accommodation, rather than self-accommodation, occurs between parent and new phases when the strength is low or the dislocation density is high for the parent phase and the invariant habit plane is difficult to form, resulting in the formation of dislocation martensites.
