摘要
综述了Al-Si合金中富铁相的存在形态、形成条件以及富铁相影响因素的研究进展,重点讨论了Al-Si合金中合金元素、熔炼铸造工艺对富铁相形态与分布影响的最新研究现状。研究现状表明,针状富铁相对Al-Si合金性能危害极大,而汉字状富铁相对合金性能的危害要小得多,合金元素和熔铸工艺对富铁相形态具有重要的影响;因此,研究合金元素与熔铸工艺对富铁相形态的交互作用及其影响规律,从而获得有益的富铁相形态,或减少合金中Fe含量是Al-Si合金中减缓富铁相危害的重要研究趋势。
The research progress of iron-rich phase morphology, formation conditions, and its influen- cing factors of iron-rich phase in A1-Si alloy was reviewed, and the latest research status of iron-rich phase morphology and distribution affected by alloy elements, melting ＆ casting process was also di- cussed. The research status shows that the needle iron-rich phase does great harm to the properties of A1-Si alloys, more severe than the Chinese-script iron-rich phase. Besides, the morphology of the iron-rich phase is significantly affected by alloy component and casting process. Therefore, the impor- tant research trend is to study the interaction and effect principle of elements and melting casting process on iron-rich phase morphology, in order to obtain the useful form of iron-rich phase or to miti gate the hazard of A1-Si alloy iron-rich phase.
