Processing maps have been developed for hot deformation of Mg-2Zn- 1Mn alloy in as-cast condition and after homogenization with a view to evaluate the influence of homogenization. Hot compression data in the temperature range 300 - 500 °C and strain rate range 0.001 - 100 s- 1 were used for generating the processing map. In the map for the as-cast alloy the domain of dynamic recrystallization occurring at 450 °C and 0.1 s-1 has merged with another domain occurring at 500 °C and 0.001 s- 1 representing grain boundary cracking. The latter domain is eliminated by homogenization and the dynamic recrystallization domain expanded with a higher peak efficiency occurring at 500 °C and 0.05 s-1. The flow localization occurring at strain rates higher than 5 s-1 is unaffected by homogenization. © 2003 Carl Hanser Verlag, München.
