摘要
综述了铸造铝合金的强韧化研究进展,重点归纳了铸造铝合金多元合金化、晶粒细化和组织纯净化方面的最新研究成果,并对相关的强韧化机理进行了评述,指出了其中所存在的不足,展望了高强韧铸造铝合金的发展趋势。
In this paper the strengthening-toughening research progress of cast aluminum alloys was summarized,in which the recent advances in cast aluminum strengthen and toughen methods such as multi-alloying,grain refinement and micro-structure purification were emphatically concluded. The corresponding strengthening-toughening mechanisms of different methods were introduced,and the deficiencies of each mechanism were also pointed out.At last,the development trends of cast aluminum with high strength and toughness were prospected.
