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
