摘要

In order to improve the understanding deformation behaviors of thermal compressive of ZK30 magnesium alloy, carried out a series of thermal compressive tests with height reduction 60% of specimens were performed at deformation temperature range of 523-673 K, and strain rates range of 0.001-1 s~(-1) on Gleeble-1500 thermo-mechanical simulator. Based on an Arrhenius-type equation constructs a nonlinear flow model and its constitutive equation, are employed to study the deformation behavior and the relationship between deformation temperature, strain rate and flow stress. For higher deformation temperature and lower strain rate, the true stress-strain curves show a characteristic of dynamic recrystallization. With the increase of deformation temperature and the decrease of strain rate the flow stress decreases, also the dynamic recrystallization becomes easier.
