Influences of Nanoparticles in Friction Stir Welding Processes

Abstract

Lightweight materials and their alloys are increasingly used in automobiles and aircraft due to their high specific strength and strength and weight ratio. The characteristics of aluminium materials and their alloys make applying traditional mechanical joining and welding processes difficult. Recently much research has been conducted to obtain reliable and high mechanical strength joints on aluminium alloys using various methods of joining process. This chapter provides a detailed review of recent research on nanoparticle-influenced friction stir welding on different aluminium alloys. The latest advancements and application of nanoparticle reinforcements in the joining behaviour of aluminium alloys are also systematically described. Finally, several unaddressed issues and future development in joining aluminium alloys with the addition of nanoparticles are included.
