EFFECT OF SOME FACTORS ON PLASTICITY OF DISCONTINUOUS REINFORCED Al MATRIX COMPOSITES
影响非连续增强 Al 基复合材料塑性的因素

SiC_w and SiC_p reinforced Al-alloy matrix composites were fabricated viavacuum hot pressure technology.This paper describes the research works on effects of workingprocess,reinforcement content,size,type and matrix alloys on the plasticity of above-men-tioned discontinuous reinforced Al-alloy composites.Moreover,a new type of complex matrixcomposite was fabricated via P/M technology.The elongation of 15v.-%SiC_p/2024Al+Alcomposite achieves 9.0%.
