Heat transfer proceeding in domain of cast composite with particles is considered. In particular the thermal processes in a sub-domain being the composition of single spherical particle (Pb) and adjoining metal matrix (Al) are analyzed. Initial temperatures of components correspond to solid state (particle) and liquid one (matrix). Numerical algorithm corresponding to a mathematical model of the boundary initial problem discussed is constructed on the basis of control volume method. In the final part of the paper the examples of computations are shown.
