In this article we will discuss about the crystallographic theory of martensitic transformation in steels. In martensitic transformation in steels, the crystal lattice changes from FCC (austenite), to BCT (martensite). The parallel reference scratches (Fig. 3.45) on prepolished surface remain parallel, straight and continuous across the austenite-martensite interface after the transformation means homogeneous deformation must have taken place. The continuity [...]
