On the study of the f.c.c.-h.c.p. martensitic transformation using a diffraction approach-II. H.c.p. → f.c.c. transformation

Abstract

Theory of diffraction from h.c.p. crystals undergoing martensitic transformation to the f.c.c. structure through a non-random insertion of deformation faults is developed. From a comparison of the theoretically predicted diffraction effects with those experimentally observed on single crystals of ZnS, it is shown that the thermally induced transformations in this material are growth controlled while the deformation induced transformation is nucleation controlled. © 1986.
