The solidification of cast composite with particles is considered, in particular the single lead particle and its spherical surroundings (metal matrix) are analyzed. The dimension of particle-metal matrix sub-domain results from the mean particles radius and the fraction of particles. On a stage of numerical modelling the finite difference method (FDM) is applied. The additional procedures simulating the course of solidification and melting are also introduced. In the final part of the paper the examples of computations are presented.
