摘　　要：采用粉末冶金工艺制备了Al-Fe-V-Si合金及Al-Fe-V-Si/SiCp复合材料,对该合金及复合材料的微观组织进行了研究,测试了合金棒材与其SiC颗粒增强复合材料的常温和高温力学性能。结果表明:制备得到Al-Fe-V-Si合金的主要析出相和强化相是弥散分布的球状-αAl13相;加入SiC颗粒后,大幅度提高了材料的抗拉强度。A1-Fe-V-Si alloy and A1-Fe-V-Si/SiCp composite were prepared by powder metallurgy process, and the microstructures were carefully studied, also the mechanical properties at both room temperature and high temperature were tested. The results show that the primary precipitate phase in this alloy matrix is α-A113, which is also the primary strengthening phase in A1-Fe-V-Si alloy. Tensile strength of A1- Fe-V-Si alloy has greatly increased by the addition of SiC particulate.
