焊接在汽车、航空航天、机器人、建筑等行业具有重要的作用.这些行业常用非焊接方法制造很多铝合金零部件或系统.然而,由于不可热处理合金的存在、孔隙、凝固和熔融裂纹等因素,铝合金的熔焊具有挑战性.许多制造商采用传统的空气搅拌摩擦焊(FSW)焊接合金和异质材料,也有许多研究报道关于该传统FSW技术在焊接金属和聚合物材料,尤其是铝合金和铝基复合材料方面的缺点.近年来,为了克服传统FSW技术焊接铝合金的缺点,开发出很多其他FSW技术,例如水下搅拌摩擦焊(UFSW)和振动搅拌摩擦焊(VFSW)等.本文综述了近年来铝合金及铝基复合材料(Al MMCs)搅拌摩擦焊接工艺的研究进展,讨论了传统的FSW技术和最先进的FSW工艺参数对铝合金和铝基复合材料焊接质量和强度的影响,并比较了每种方法的优缺点.VFSW在能源效率和经济成本方面具有优势,并可根据应用情况进行多种改进,是焊接铝接头的一种可行的选择.然而,目前对Al MMCs搅拌摩擦焊的研究明显较少,这应给予足够的关注.
Review of recent trends in friction stir welding process of aluminum alloys and aluminum metal matrix composites
Welding is a vital component of several industries such as automotive, aerospace, robotics, and construction. Without welding, these industries utilize aluminum alloys for the manufacturing of many components or systems. However, fusion welding of aluminum alloys is challenging due to several factors, including the presence of non-heat-treatable alloys, porosity, solidification, and liquation of cracks. Many manufacturers adopt conventional in-air friction stir welding (FSW) to weld metallic alloys and dissimilar materials. Many researchers reported the drawbacks of this traditional in-air FSW technique in welding metallic and polymeric materials in general and aluminum alloys and aluminum matrix composites in specific. A number of FSW techniques were developed recently, such as underwater friction stir welding (UFSW), vibrational friction-stir welding (VFSW), and others, for welding of aluminum alloy joints to overcome the issues of welding using conventional FSW. Therefore, the main objective of this review is to summarize the recent trends in FSW process of aluminum alloys and aluminum metal matrix composites (Al MMCs). Also, it discusses the effect of welding parameters of the traditional and state-of-the-art developed FSW techniques on the welding quality and strength of aluminum alloys and Al MMCs. Comparison among the techniques and advantages and limitations of each are considered. The review suggests that VFSW is a viable option for welding aluminum joints due to its energy efficiency, economic cost, and versatile modifications that can be employed based on the application. This review also illustrated that significantly less attention has been paid to FSW of Al-MMCs and considerable attention is demanded to produce qualified joint.
