Monte Carlo techniques are employed to study the kinetics of h.c.p. (2
H) to f.c.c. (3C) martensitic transition by spin flip dynamics using a
1-D (one-dimensional) Ising model. The characteristic length scale is
shown to exhibit t(0.5) dependence as confirmed by direct domain coun
ting as well as dynamical scaling of the pair correlation functions. T
he diffuse scattering at]ate stages can be predicted using a scaling f
unction for the pair correlations. The predicted evolution of the diff
use scattering pattern for the spinodal regime is in qualitative agree
ment with the experimentally observed patterns for ZnS single crystals
