| 中文摘要: |
| 由于铝、钢的物理化学性质存在巨大差异，铝/钢的连接是焊接领域的难点问题。搅拌摩擦焊是低热输入的固态连接方法，能够有效控制铝/钢金属间化合物的生长，且搅拌针强烈的搅拌作用可增加铝/钢异种材料机械咬合程度，得到高质量的铝/钢焊接接头，铝/钢搅拌摩擦焊已经成为了焊接领域的热点问题。文中综述了铝/钢搅拌摩擦焊国内外研究现状，涉及到接头形式、焊缝成形、焊接工艺和力学性能，着重介绍了铝/钢搅拌摩擦焊接头的连接机制，并围绕铝/钢搅拌摩擦焊存在的两大问题，对铝/钢搅拌摩擦焊新技术进行总结，并进一步提出了铝/钢搅拌摩擦焊的基础研究方向。 |
| 英文摘要: |
| The joining of aluminum and steel is a great challenge in the field of welding due to large differences in physical and chemical properties of aluminum alloy and steel. Friction stir welding (FSW) is a solid-state joining method with low-heat input, which can effectively control the growth of Al/Fe intermetallic compounds and the strong stirring effect of pin can enhance the mechanical interlocking at aluminum/steel interface. High quality aluminum/steel dissimilar joints could be obtained by friction stir welding. FSW of aluminum/steel has become a hot issue in the field of welding. The research situation of aluminum/steel friction stir welding at home and abroad was presented in this paper, which was involved joint configuration, weld formation, welding process and mechanical properties. Particular emphasis was given to the joining mechanism of aluminum/steel joint by FSW. Based on the two existing problems in Al/steel FSW, new technologies based on traditional FSW were summarized. Furthermore, the trend of foundation research on aluminum/steel FSW was discussed. |
