Investigations on the Effect of Tool Speed and Feed Rate on the Friction Stir Processed AZ31B Magnesium Alloys

The friction stir processing is a solid state processing technique. The present study investigates the effect of process parameters like tool rotational speed and tool feed on the mechanical and tribological properties of friction stir processed AZ31B magnesium alloy. The experiments were conducted with 3 level 2 factors full factorial design with two replications. The responses were tensile strength, microhardness and wear. The investigation reveals that both the tensile strength and microhardness values were decreasing with decreasing grain size. The minimum wear rates were observed at higher hardness values.
