“…The calculated intensity distribution variation, representing the martensitic h.c.p. In order to investigate 2H single crystal of SiC, ZnS, Zn x Cd 1-x S and Zn x Mn 1-x S undergoing solid state transformation to 6H(33) structure, the diffraction theory of 2H to 6H transformation was developed, among others, by PANDEY (1980aPANDEY ( , 1980bPANDEY ( , 1980c, SEBASTIAN (1983SEBASTIAN ( ), (1987 and KABRA (1989). transformation by means of deformation SFs, according to our simplest Model 1 (R = 2), is depicted in Fig.…”
