Friction extrusion process is a newly developed solid-state processing method and emerging as a potential processing method of microstructural modification to improve mechanical properties. Friction extrusion process has been utilized to generate metal matrix composite (MMC) microstructures in Al alloys to achieve better strength and ductility simultaneously. Ceramic powders (Al2O3 and MgO) with 5, 10 and 15 vol% were used to get Al MMC microstructures. Composites were extruded in the form of 5 mm diameter rod. Quantitative microstructural characterization was performed using scanning electron microscopy (SEM), back-scatter electron microscopy (EBSD) and transmission electron microscopy (TEM) to understand the distribution of the ceramic particles in Al matrix in the extruded rods. Mechanical properties of MMCs were evaluated by performing compression and tensile tests of the extruded rods.
