Research Status and Prospect of Friction Stir Welding of Magnesium-Alumi-num Dissimilar Alloys
摘要
Abstract
Magnesium alloys are widely used in various engineering fields because of their high specific strength and stiffness.Howev-er,magnesium alloys have some disadvantages such as easily corroded and poor formability,which greatly restrict the wide application of magnesium alloys.Aluminum alloy density is low density,high strength,close to or more than high-quality steel,good plasticity,can be processed into various profiles,with excellent electrical conductivity,thermal conductivity and corrosion resistance,widely used in industry,the use of second only to steel.Welding of dissimilar alloys is considered to be one of the most complicated engineering in aerospace,rail transit and automobile industries.Through the welding of Mg-Al dissimilar alloys can take advantage of the advantages of the two alloys at the same time,so as to meet the requirements of some special working environments for parts.At the same time,the welding of Mg-Al dissimilar alloys can significantly save materials and reduce costs,and greatly expand the application of magnesium and aluminum alloys.Friction stir welding(FSW)can significantly improve many metallurgical problems existing in traditional fusion welding process,so as to obtain high quality welded joints.Therefore,friction stir welding of magnesium-aluminum alloy with different brands not only has great scientific research value,but also has great industrial application value.This paper reviewed the research progress of friction stir welding of magnesium aluminum alloy,especially the influence of friction stir welding process parameters on mi-crostructure evolution,mechanical properties and related defects,and the future research hotspots were prospected.关键词
