摘　　要：熔体混合处理作为一种工艺简单、成本低廉、对环境影响较小的生产工艺,为优化Al-Si合金凝固组织提供了一条新的思路。对熔体混合处理工艺进行了简要的介绍,综述了国内外利用熔体混合处理工艺细化Al-Si合金凝固组织、优化初生相分布及形貌的研究现状,并对其作用机制进行了概述,最后对其暂不能用于工业化生产的原因进行了分析。Melt mixing treatment process has the characteristic of simple technology and low-cost as well as small negative effect on the environment,provided a new idea to optimize the solidification structure of Al-Si alloys.Melt mixing treatment process has been briefly introduced.The progress was reviewed, including the solidification structure of Al-Si alloys,the distribution and morphology of primary phase. The mechanism of melt mixing treatment on optimizing the solidification was summarized.The reason of melt mixing treatment difficult to industrial production was analyzed.
