摘　　要：对近年来5154铝镁合金线材晶粒细化技术的研究开发进行了阐述,从材料成分设计优化与晶粒细化技术两个方面,详细分析了变质处理、电场细化、表面技术处理、热处理工艺与拉拔道次优化等技术措施,总结了从合金成分、制备工艺到晶粒细化处理的优化措施,并对合金向超强超细化发展中存在的问题及研究的技术路线进行了探讨。Progress in grain refining technology for 5154 aluminum magnesium alloy wire rods in recent years was surveyed. From two aspects of alloys material composition design optimization and the grain refinement technology, some measures, such as modification treatment, electric field refinement and surface treatment, heat treatment process and optimization of drawing-pulling pass, were described. Op- timized ways of alloy chemical composition, preparation technology and grain refinement process were summarized. The problems in the development of ultra-fine and super-strength tendency and the corre- sponding technical route were approached.
