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 …

A framework for shear driven dissolution of thermally stable particles during friction stir welding and processing

A framework is proposed to explain the dissolution and fragmentation of particles during friction stir welding and processing. Two major mechanisms dissolve the particle during the process: (i) thermally activated diffusion, and (ii) dislocation and …

Experimental characterization of metal matrix composite with aluminium matrix and Molybdenum powders as reinforcement

This paper is on the successful fabrication of Metal Matrix Composite (MMC) using an Aluminium plate and Molybdenum powder by Friction Stir Process (FSP). The aim was to produce a superficial MMC layer on the Al plate in order to increase the …
