“…There are various flaws in the joint quality of AMCs welded using traditional fusion welding techniques. Fusion welding causes the production of detrimental phases in the joint region as a result of excessive heat, cracking, deformation, porosity, and the settling of hard particles at the bottom of the weld zone as a result of the difference in densities [6][7]. An advantageous joining approach for AMCs appears to be a solid state welding process.…”

A significant area of research now being pursued by the foundry industry is how to enhance the mechanical properties of aluminium alloys by reinforcing them with micro ceramic particles. The mechanical and Microstructural studies of commercial AA 7075 stir die castings reinforced by various weight ratios of titanium carbide (TiC), boron carbide (B4C), and aluminium oxide (Al2O3) have been examined in the current study. Further, friction stir welding (FSW) process has been carried out based L16 Orthogonal Array (OA). Optimal decision making approach for the improvement of Friction Stir Welding (FSW) process was performed by Taguchi method. Investigations were conducted on the effects of three variables on UTS, including rotating speed, transverse speed and tilt angle. The maximum ultimate tensile stress was found to be around 162 M Pa for sample 8 (1.5 wt% TiC, 0.5 wt% B4C and 0.8 wt% Al2O3) welded at speed 900 rpm, feed 45 mm/min, and Tilt angle 2.50.

“…AMCs joined through conventional fusion welding methods unveils several short comes in terms of quality of joints. Fusion welding leads to the formation of harmful phases in the joint region due to excessive heat, cracking, porosity, distortion and settling of hard particles at the bottom of the weld region due to the difference in densities [5][6][7]. A solid state welding process seems a favorable joining method for AMCs.…”

Friction stir welding (FSW) is established as one of the prominent welding techniques to join aluminium matrix composites (AMCs). It is a solid state welding process, takes place well below the melting temperature of the material, eliminates the detrimental effects of conventional fusion welding process. Although the process is capable to join AMCs, challenges are still open that need to be fulfill to widen its applications. This paper gives the outline of the friction stir welding technique used to join AMCs. Effect of process variables on the microstructure and mechanical properties of the joints, behavior of reinforcing materials during welding, effect of tool profiles on the joint strength are discussed in detail. Few improvements and direction for future research are also proposed.
