Description
Friction stir welding (FSW) experiments were undertaken to investigate the feasibility of joining a metal matrix composite (MMC), comprising an AA 2124 matrix and 25 vol.% SiC particles, to itself and to a monolithic alloy (AA 2024-T3), and the microstructure and mechanical properties of the welded joints were examined. FSW tool wear was reduced by optimising process parameters and by applying a wear resistant coating on both the shoulder and the pin. Dissimilar joints were fabricated with the MMC on either the advancing or retreating side. Microstructural features of welded joints and fracture surfaces were observed by optical microscopy. Mechanical properties were characterised by Vickers hardness profile measurements and tensile testing on an Instron 4505 screw driven test machine.
