摘    要：采用喷射成形技术制备Al-Si系合金可以明显细化初生Si相和显微组织,得到低偏析、高致密度、低含氧量且具有高性能的合金材料。主要介绍喷射成形技术的基本原理及其在Al-Si系合金的应用与研究现状,分析了目前存在的问题并提出了今后的发展方向。

Abstract: Al-Si alloys produced by spray forming process,which could refine primary silicon phase and microstructure,exhibited low micro segregation,high compactness,low oxygen content and excellent workability. The basic mechanism of spray forming process and the research progress of the application to Al-Si alloys were introduced. The relevant problems and development trend were also addressed.
