Research Progress in Friction Welding of Magnesium Alloy

Abstract

The basic principles and features of friction welding were introduced.The research progresses in friction welding of Mg alloys were reviewed. The process, joining mechanism, microstructure and mechanical properties of Mg-Mg similar and Mg-Al dissimilar friction welded joints were primarily discussed. Meanwhile, the current problems were analyzed. It was pointed out that the temperature field, stress-strain field and plastic flow during the friction welding process of Mg alloys require further investigation. Furthermore, the future development should focus on the optimization of process and intermediate layer to obtain high quality joints.
