摘　　要：元素Be的加入使铸态Al-Fe-V-Si合金中粗大针状的铝铁相得到明显改善,基体晶粒得到细化,力学性能提高。在分析试验结果的基础上,对不同Be添加量的细化变质效果做了比较,综合来看,加入1.28%Be的合金中针状铝铁相已经消失,基体晶粒细小,力学性能较好。The effects of different amout beryllium on microstructures and mechanical properties in Al-Fe-V-Si alloys are investigated. The results show that the addition of beryllium can ameliorate needle-like Al-Fe-phases evidently, refine grains, improve mechanical properties. As a whole, the alloy containing 1.28% Be makes needle-like Al-Fe-phase disappeared and has smaller grains and better mechanical properties.
