摘　　要：为了探究硅铝合金材料应用需求,采取热压致密化和喷射成形法,制备硅铝合金,并利用热膨胀仪、金相显微镜等设备对材料的热物理性能、力学性能及显微组织进行研究。结果发现,在铝基体中分布较为均匀、弥散;热压致密化能够改善喷射成形存在的弊端,促进材料致密度的提升,材料具备良好的力学及物理性能。Application requirements to explore silicon aluminum alloy material, adopts the hot-pressing densification and spray forming, the preparation of silicon aluminium alloy, and by using thermal expansion instrument, metallographic microscope and other equipment on the material＇s thermal physical properties, mechanical properties and microstructure were studied. The results show that in the aluminum substrate distribution is relatively uniform, dispersion; Hot-pressing densification can improve the insufficiency of injection forming, promote improvement of material density materials have good mechanical and physical properties.
