Friction Welding Studies on SiCp Reinforced Aluminium Alloy AA 2124 Metal Matrix Compositie

Continuous drive friction welding studies were carried out on AA 2124 SiCp metal matrix particulate composite. Taguchi technique was employed to select the best combination of friction welding parameters. Studied the influence of main friction welding process parameters such as friction force, forge force and burn off on tensile properties. Low friction force, high forge force and high burn-off yielded maximum tensile strength. Friction welds of metal matrix composite with higher volume fraction of SiCp yielded high tensile strength. It was observed that tensile strength of the welds were stronger than the corresponding parent material. The higher tensile strength of the welds is thought to be due to the break down of the reinforcement particle.
