Warm forging to near net shape shows promising benefits in terms of microstructure refinement and texture modification. In the present study, compression tests were performed to investigate the influence of forging at a deformation rate of 0.4 mm/s and a temperature of 400°C on the performance of extruded AZ80 magnesium alloy. The obtained microstructural analysis showed that the extruded AZ80 magnesium alloy possesses typical wrought grain structure with sharp texture. In contrast, the forged samples showed refined grains and a variation of texture from stronger to weak depending on the location of the sample. The monotonic compression results in the extrusion direction showed that the forged sample obtained a maximum strength and ductility of 446 MPa and 0.13, respectively which was higher than the as-extruded materials at the same orientation. It is believed that forging causes grain refinement and texture modification which enhance the alloy performance.
