In the present work, kinetic equations of dynamic recrystallization and high-temperature deformation mechanism equationswere coupled to calculate and construct processing maps for metallic alloys in 2D and 3D. The validity of this method wasconfirmed for selected materials (Mg and Fe alloys) by comparing the calculated processing maps with those constructedbased on experimental data. The effect of the initial grain size on the processing maps was predicted. The proposed analysismethod is innovative because the processing map for a material of interest can be calculated as a function of strain rate,temperature and strain under any deformation condition once the dynamic recrystallization kinetics and the creep deformationequations for the material are known. Furthermore, the proposed method can provide information regarding the ratecontrollingcreep deformation mechanism and microstructural evolution at any location on the processing maps.
