摘要
采用粉末混合 -半固态挤压工艺制备SiCp 2 0 2 4Al复合材料棒材 ,对其微观组织、力学性能和断口形貌进行了分析 .SEM电镜观察结果表明 ,该工艺能够制得SiC颗粒分布均匀、基体组织致密、界面结合良好的复合材料棒材 .采用Instron材料实验机对复合材料力学性能进行测试 ,结果表明 ,其力学性能与基体合金相比有较大提高 ,复合材料的塑性相对较高 .同时 。
Presents the microstructures, mechanical properties and defects SiC p/2024 Al composites produced by semi solid extrusion technology and concludes that SiC p/2024 composites can be characterized by well densified matrix with uniformly distributed reinforcement particles, and there is no apparent interface reaction; The mechanical properties of the composites are higher than those of the matrix; SiC p/2024Al composites fabricated by the technology possess relatively high elongation.
