Abstract Scope |
Bobbin Friction Stir Processing (BFSP) is a technique used to engineer the microstructure of materials through severe plastic deformation and Dynamic Recrystallization. In the current work, we utilized BFSP to engineer the properties of 3 mm thick AZ31B magnesium alloy plates. The controlled process parameters were rotational speed and translational speed. The translational speed was held constant at 10 mm/min while rotational speed was varied from 1400 rpm to 2000 rpm. A defect-free coupon was obtained in which grain refinement of 30% of BM and texture strengthening was observed. Vickers microhardness of the coupons showed certain peak values in the stir zone. Tensile testing results were in accordance to the observed microstructural details, where highest tensile strength of 196 MPa and yield strength of 106 MPa was observed at room temperature. Results suggest BFSP is a potential tool to engineer microstructure and mechanical properties of magnesium alloys. |
