Feasibility of joining AZ31B magnesium metal matrix composite by friction welding
Abstract The present study investigates the feasibility of joining AZ31B magnesium nanocomposites by rotational friction welding. The AZ31B magnesium metal matrix composite, which was reinforced with alumina (Al2O3, average particle size of 50nm) and calcium (Ca), was produced by a hybrid casting process and hot extruded at 350°C. Joining processes were done by varying the friction welding parameters. The integrity of the joints was investigated by optical microscopy. The mechanical properties of the joints were examined by tension tests and micro hardness tests. The efficiencies of the joints were analysed using statistical analysis. The fracture mode was studied using a scanning electron microscope. It was observed that as the friction pressure and forging pressure increased, the joint efficiency increased. Also, as the friction time increased, the efficiency of the joint decreased.
