Abstract: A modified WLR method for bcc to monoclinic transformations has been developed. With the aid of computer,the habit planes,the magnitude of the lattice invariant shear,rotation matrix and the total transformation matrix have been calculated for five alloys being in good agree- ment with the observations.

Key words: martensitic, transformation, phenomenological crystallographic theory
