本文探讨了用搅拌铸造法，采用常规的熔炼加工设备和工艺，制造ＳｉＣ颗粒增强铝基复合材料的可行性；研究了不同ＳｉＣ含量的复合材料的显微组织；试验表明：复合材料中ＳｉＣ颗粒分布较为均匀，其力学性能均优越于基体合金，弥散分布的ＳｉＣ颗粒是复合材料力学性能优异的主要原因。 In this paper, we discuss the feasibility of manufacturing SiC particle reinforced aluminum matrix composites by the method of stirring casting, conventional smelting processing equipment and technology. The microstructures of SiC composites with different SiC contents are studied. The results show that SiC particles The distribution is more uniform, the mechanical properties are superior to the matrix alloy, the dispersion of SiC particles is the main reason for the excellent mechanical properties of composite materials.
