ABSTRACT:
An easy method and apparatus to eliminate casting defects from composite materials of hypereutectic Al-Si alloys and improve their properties. The product composite materials with primary silicon crystals of several microns have fine honogeneous microstructures and mechanical properties comparable to similar materials produced by the conventional powder metallurgy technology. Highly wear-resistant composite materials, in which the hypereutectic Al-Si alloy and strengthening material are homogeneously mixed, can be obtained with ease. The hypereutectic Al-Si alloy and strengthening material are homogeneously mixed by stirring blades rotated at low speed. The obtained molten composite alloy rotated at high speed about a horizontal shaft in a heat-resistant vessel. The rotor rotating and stirring at high speed spatters the molten composite alloy material to break up the crystallizing out primary silicon crystals. The rotor stirs the spattered semi-solid composite alloy material received by the heat-resistant vessel. A resulting semi-solid mass having a fine-grained homogeneous microstructure is recovered as the final product.
