A Review on Friction Stir Processing ofMagnesium Alloys
Abstract
Friction Stir Processing (FSP) works on principle of Friction Stir Welding. Through intense localized plastic deformation FSP changes properties of materials. Surface properties, such as wear resistance, hardness and strength can determine the service life of components in many industrial applications. The paper reviewed different factors affecting magnesium alloys during FSP. Magnesium alloys are used in variety of different applications. They are used when looking for weight reduction without compromising overall strength. Magnesium alloys are also used in automotive, aerospace applications. In this process we can make different solid state process composition in which single phase as well as multi-phase composition can be formed. In two phase surface composition different additives like SiC, CNT, B4C, etc can be used. In this review article we studied that FSP can be done by considering factors like tool material, rotational speed, processing speed. FSP modifies microstructure of single component or multipleworkpieces.
