Abstract
A computer model for simulating solidification and involving a Monte Carlo procedure has been used to qualitatively predict the influence of solidification conditions on the grain structures of small castings. In agreement with experimental observations, it was found that increasing either superheat or mould temperature results in coarsening of the grain structure. This agreement supports the contention that the principal mechanism of equiaxed grain formation in small castings is heterogeneous nucleation. The model also illustrates the importance of simulating equiaxed grain movement in the bulk liquid in order to obtain realistic predictions of grain structures.
