【Abstract】 The rapid solidification technique of particulate-reinforced alu-minium-matrix composites is a new-type composite material technique recently de-veloped for the purpose of combining the advantages of material composition and rapid solification. Presently ,most of the research on processing of these materials is stili at an embryonic stage, and the emerged manufacturing techniques mainly are rapid solidification molten casting, powder metallurgy and spary deposition. In this paper, these techniques are analyzed, compared and evaluated in their salient fea-tures of technological process and material preparation.更多还原
