The coupled multi-level modeling is proposed and developed to directly describe the hierarchical structure of superplasticity. Through the hierarchical linkage between macro-and micro-models, the effect of mesoscopic microstructure on the product-level hot deformation can be taken into account together with direct consideration of the applied stress effect on the microstructure evolution. Hence, macroscopic properties can be estimated from the calculated configuration of microstructure. Through the coupling between hot deformation and thermal transients, both macroscopic and mesoscopic hot deformation behavior can be described under any thermal loading.
