Abstract © The Minerals, Metals & Materials Society 2018. Bulk metallic glass and their composites are unique new materials which have superior mechanical and structural properties as compared to existing conventional materials. However, their mechanical behavior is dubious, unpredictable and requires extensive experimentation to draw conclusive results. In present study, which is continuation of previous work of author, a non-linear one-dimensional iterative deterministic model is combined with two-dimensional probabilistic cellular automaton method to describe nucleation and growth of primary ductile phase from melt in glassy matrix during solidification. Preliminary methodology ad philosophy of model making is described with an aim to explain the grounds on which this approach is adopted. MATLAB® is chosen as programing platform. Results indicate that the effect of incorporating all heat transfer, mass transfer and diffusion coefficients with appropriate interpolation play a vital role in refining the model and bringing it closer to actual experimental observations. Two types of hypo and hyper eutectic systems were studied with different inoculants.
