摘　　要：主要研究了不同Ce中间合金对A356铝合金的细化变质的效果,结果表明:Al-10Ce和Al-4Ti-4Ce-B中间合金对A356合金具有较好的细化变质效果,Al-5Sr-5Ce中间合金对A356的细化变质效果不够理想,而Al-10Sr中间合金的添加对Al-4Ti-4Ce-B中间合金的细化变质具有促进作用。本文还进行了Ce对A356合金细化变质机理的探讨。The effect of modification of different Ce master alloys on A356 Al alloy have been investigated.The results showed that Al-10Ce and Al-4Ti-4Ce-B master alloys presented good modification effect to A356 alloys,while Al-5Sr-5Ce showed bad modification effect to A356 alloys.Moreover,the addition of Al-10Sr master alloy promoted the effect of modification of Al-4Ti-4Ce-B for A356 Al alloy.The modification mechanism of Ce to A356 alloy has also been discussed.
