Forging is a common method employed in the fabrication of automotive components. In this study, extruded AZ31B magnesium alloy was semi-close die forged at a temperature of 500 °C with a rate of 0.4 mm/s followed by microstructure analysis and uniaxial compression testing. Microstructural study indicated a refined grain structure in the forged samples compared to the bi-modal grain structure in the as-extruded sample. Also, the forged samples exhibited strong to weak texture depending on the location in the forged component. The obtained compression results showed a remarkable improvement of fracture strain of 16.8% in the forged samples compared to the extruded samples (9.1%), while an ultimate compressive strength of 236.7MPa and 287.6MPa was observed along the radial direction of the forged and as-extruded samples, respectively. It is attributed that the modification of microstructure and texture decreases the twinning and increases the slipping activity resulting the improvement of ductility.
