【摘要】 综述了当前国内外铝硅合金变质处理及其变质机理的研究进展。变质元素Na、Sr、Sb、Ba、Te、Bi、P、S、Ca、As、稀土等已取得了良好的变质效果,通过对比分析其变质机理以及绿色无污染、经济长效等方面的优缺点,比较了这些变质元素单一变质、二元变质和多元变质的优势与局限性,并展望了铝硅合金变质方法的发展趋势。更多还原

【Abstract】 The current modification developments of Al-Si alloy are described.Some modification elements(Na,Sr,Sb,Ba,Te,Bi,P,S,Ca,As,RE,etc) have good treatment effects.The advantages and limitations of these elements,as well as their multi-modification are evaluated through analyzing their modification mechanism,non-pollution,cost and long term effect.Moreover,the developing trend of Al-Si alloy modification is predicted.更多还原
