In this work author showed the diversification of structure for cast dispersive AlSi-CrxCy composites. Wide possibilities of properties control and optimization were described, through microstructure of the matrix and the transition zone shaping. Utility castings were prepared with use of traditional casting techniques, ceramic and metal moulds. The influence of technological conditions and cooling rate ion the composite structure was studied. The main factor of structural changes was the diffusion at matrix – reinforcement interface. Divers structure was observed in particle close neighborhood. Possibilities of diffusion control were indicated through application of factors assisting the crystallization.
