Abstract

Purpose: The alloy needed for friction stir welding must be able to fracture during the solidification and joining processes. To overcome some of these problems solid state welding processes have been identified as alternative and Friction stir welding process (FSW) is one found to be more prominent to join simple to complex geometries. In this investigation, FSW of AZ91D magnesium alloy is undertaken with cerium microparticles embedded into the weldment in order to produce a metal matrix composite at the stir zone. Design/methodology/Approach: AZ 91D magnesium alloy materials are friction welded by keeping cerium powder between the plates to be joined before the joining process. Magnesium alloy is the type of raw material that used for various mechanical industries since it has the good thermal conductivity, and lightweight. The solid state joining process employs friction stir welding. The commercial Mg alloys consists of various elements like Al, Mn, and Zn. Taguchi L9 OA is employed for the experimentation and three factors namely rotational speed, Feed of Tool and tilt angle of tool are used. The results are analyzed with entropy weighted TOPSIS method. The overall outcome is predicted and confirmation test results are compared with it.
