摘要
对国内外Al-Sc合金的发展历史和现状进行了概括。讨论了发展钪及铝钪合金中存在的一些问题,并总结了一些解决方法。简要阐述了钪对铝的很好弥散强化作用,是铝合金强有力的晶粒细化剂和有效的再结晶抑制剂。钪在铝及铝合金中同时具有稀土金属和过渡族金属类金属的有益作用,但其效果却比这2类金属明显得多,铝钪合金的开发有望逐步扩大应用。
The history and current development status of Al-Sc alloy in China and abroad are reviewed. The existing problems in scandium and Al-Sc alloys are discussed. And some methods are summarized. The paper introduces briefly that scandium have good dispersion strengthening effect and can be used as grain refiner and effective recrystallization inhibiter of aluminum alloy. Scandium in Al-Sc alloy has action which is equal to rare metal and metal in transition metals but effects are more obvious than above metals.he development and application of Al-Sc alloy briefly discussed.
