Abstract Microstructures and mechanical properties of AZ91 magnesium alloy after homogenized, hot extrusion and succedent aging are investigated. The results show that dynamic recrystallization occurs during extrusion at elevated temperatures of 320℃ and 380℃; compared to the as-cast alloy, microstructures of the extruded AZ91 alloy are refined, and the mechanical properties are enhanced remarkably; succedent aging is helpful to improvement of mechanical properties of the extruded AZ91 alloy. In this experiment, the ultimate tensile strength of the AZ91 alloy extruded at 380℃and aged at 200℃×10h is about 357MPa, and the elongation of the alloy reaches about 8%.
