Diffraction effects from h.c.p. crystals with random growth faults undergoing transformation to the f.c.c. phase by the deformation mechanism

Abstract

Hexagonally close-packed cobalt crystals often contain a random distribution of growth faults. The h.c.p. to f.c.c. transformation is effected by a non-random insertion of deformation faults at two layer separations. The kinematical theory is developed of diffraction from h.c.p. crystals containing randomly distributed growth faults undergoing a transformation to the f.c.c. phase. The presence of a small amount of random growth faults give rise to an additional broadening of some of the reflections.
