Abstract
Calculation of diffuse scattering during h.c.p. to f.c.c. martensitic transition by non-random insertion of deformation faults using a Monte Carlo technique is presented. It is shown that a coherent modulation of wavelength lambda = 6d(111) Can result during such transitions. The intensity and sharpness of the satellite peaks are shown to depend on the volume fraction of the twin-related f.c.c. variants. The predicte d satellite peaks are in good agreement with those observed in Co and Co-Ni single crystals undergoing h.c.p. to f.c.c. martensitic transiti on. Copyright (C) 1996 Acta Metallurgica Inc.
