Influence of Traverse Speed on Formability Limits of Friction Stir Processed Mg AZ31B Alloy

G.Venkateswarlu

AZ31B alloy sheets under plane strain condition has been investigated. Friction stir processing was carried out at traverse speeds in the range of 24 mm / min to 40mm / min with a constant rotational speed of 1150 rpm. Limiting the dome height test (LDH) has been carried out to find the formability of the material under plane strain condition. The results indicate that the traverse speed is the most significant factor for refining the material, thereby improving the formability and found that the optimal traverse speed gives highest formability.
