Abstract
The wrought magnesium alloy ZK60 is extruded with and without prior homogenization treatments. Homogenization at 400 °C leads to effective dissolution of second phase particles whereas homogenization at 300 °C has little effect on them. These particles are broken down during the subsequent extrusion and play an important role in the dynamic recrystallization response of the alloy. Microstructure and mechanical properties after extruding with and without homogenization treatments are compared.
