Effect of Tool Shoulder Diameter on the Surface Hardness of Aluminum-Molybdenum Surface Composites Developed by Single and Double Groove Friction Stir Processing

Molybdenum (Mo), possessing higher hardness compared to aluminum (Al), is used for the surface hardness improvement in Al 1050 alloy. Al-Mo surface composites are developed using friction stir processing with different tool shoulder diameters. Single …
