| 摘 要： | 对碳化硅颗粒进行表面氧化酸洗处理，采用粉末冶金加热挤压工艺制备了12％SiCp／Al（体积分数）复合材料。利用金相显微镜和电镜对微观组织进行了观测，拉伸试验测试复合材料的力学性能。试验结果表明：SiC颗粒在铝基体中分布比较均匀；T6热处理条件下12％SiCp／Al复合材料的屈服强度和抗拉强度分别约为472．4MPa、525．7MPa，伸长率为6．5％，弹性模量为92．7GPa。 |

| Abstract: | The oxidized and acid dipped SiC particles reinforced Aluminium matrix composites 12%SiC_P/Al(volume fraction) have been fabricated by power metallurgy plus hot extrusion.The mechanical properties of the composites were tested by tensile tests,and their microstructures were observed by OM,SEM and TEM.The experimental results indicate that SiC particles distribute homogeneously in the matrix,and the tensile strength,yield strength,elongation and elastic modulus of the composites under T6 heat treatment are 472.4 MPa,525.7 MPa,6.5% and 92.7GPa respectively. |
