<p>During the multipass hot processing of alloy steel, restoration processes such as static and dynamic recrystallization and recovery occur. Owing to these phenomena, flow stress characteristics are affected by various deformation conditions, such as temperature and accumulated strain. The objective of this research is to develop a mathematical model for predicting flow stress to represent these effects by simply considering the processing history and restoration. Hot compression experiments were conducted and the results were compared with the predicted results. It was found that the prediction accuracy can be improved by simultaneously considering the effects of accumulated strain and restoration.</p>
