| Abstract | The study starts from a new constitutive equation able to reproduce the stress-strain curves for each strain rate and temperature. Using this equation, the characteristic parameters of dynamic recrystallization for each of the flow curves can be obtained. An experimental study of final grain sizes, their frequency and distribution and area fractions has been made. These parameters together with those mentioned above allow establishing predictive models for the final microstructure conditions of polycrystalline metallic materials. These models have been applied to the hot deformation of AZ31 magnesium alloy. Mean final grain sizes, area fraction distributions and their frequency are predicted. In addition, the characteristic dynamic recrystallization parameters of the material that constitute elements of control of the deformation process are also predicted. |
