The phenomenological theory of martensite crystallography is based on the observation that the habit plane is an invariant plane in which all lines in it are neither distorted nor rotated by the displacement vector of the invariant plane strain. The structural change is effected by a Bain deformation which follows intuitively from the orientation relationship and through which atomic interchanges do not occur. A lattice invariant deformation is also incorporated to insure that the martensite-parent interface is semicoherent and glissile. These factors and the orientation relationship as well are uniquely interrelated within the theoretical framework and must be so for any transformation alleged to follow the theory.
