摘要
钛合金具有优异的性能,在航空、航天、军工以及生物医学等领域被广泛应用。采用搅拌摩擦焊方法焊接钛合金,可以避免熔焊方法带来的焊接缺陷,因而具有潜在的应用前景。文中从焊具设计、微观组织、力学性能及焊接温度场等几个方面,系统地介绍了钛合金搅拌摩擦焊的研究现状,以便为相关研究提供有益的参考。
Titanium alloys are widely applied in aeronautic,astronautic,military and biomedical fields due to their excellent performances. Friction stir welding of titanium alloys can removed the welding defects associated with fusion welding process,which has a prospective application. In this review,the progress in the FSW of titanium alloys was introduced in detail from the four aspects of welding tool design,microstructure characteristics,mechanical properties and welding temperature distribution,which can offer an effective reference for the authors to carry out relational researches.
