Abstract
The effect of friction stir process (FSP) parameters on the microstructure and mechanical properties of AM60B magnesium alloy was investigated in this paper. The alloy was friction stir processed with rotation speed of 1600 rpm and three traverse speeds of 100 mm/min, 200 mm/min and 300mm/min. FSP results in remarkable homogeneous microstructure and grain refinement of the AM60B magnesium alloy. With the traverse speed increasing, the average grain size decreases in the stir zone (SZ). The Vikers hardness of SZs in all FSPed samples is higher than that of the base material (BM). Higher FSP traverse speed resulted in coefficient of friction of 0.012 and wear rate of 0.008 mg/m, and in the load 80 N and sliding velocity 0.2 m/s, the wear mechanism is mainly abrasion wear in all samples.
