摘　　要：铝/钢异种材料复合能同时发挥铝合金和钢的优点,铝/钢复合是实现"轻量化"的有效手段。归纳了铝/钢异种材料搅拌摩擦焊接的研究进展,综述了铝/钢异种金属搅拌摩擦焊的国内外研究现状。在对铝/钢接头内金属间化合物形成机理及控制方法,搅拌摩擦焊接过程中原子的扩散行为以及对于原子扩散的影响等方面的研究进行了论述,并对未来的研究方向进行了展望。The composite use of aluminum/steel dissimilar materials can simultaneously exert the advantages of aluminum alloy and steel, and the use of aluminum/steel composite structural parts is an effective means to achieve "lightweight". The research progress of friction stir welding of aluminum/steel dissimilar materials was summarized, and the research status of aluminum/steel dissimilar metal friction stir welding at home and abroad was reviewed. There exists insufficient theoretical research on the formation mechanism and control method of intermetallic compounds in aluminum/steel joints, as well as the diffusion behavior of atoms during friction stir welding and the influence on atom diffusion, and prospects for future research directions were carried out.
