In this research, friction stir processing of AZ31B magnesium alloy of 6 mm thickness was done in submerged conditions. The process parameters, i.e. tool pin profile (simple cylindrical, stepped cylindrical, stepped square), rotational speed ranging from 800 to 1200 rpm and traverse speed ranging from 0.5 to 1.5 mm/sec were optimized using the multi response optimization technique. The experiment was conducted with L27 orthogonal arrays. The Immersion test and hardness have been considered as output response. From the view of an application, it would be more significant to optimize the Immersion Corrosion rate and Hardness of Submerged Friction Stir Processed AZ31B alloy. Thus, this study aims at optimizing the process parameters, including various tool pin profiles, feed rates and rotational speeds with corrosion rate and micro hardness using TOPSIS. Using analysis of variance (ANOVA), the most significant parameter effect of the submerged friction stir processing was determined.
