| Abstract Scope |
Accurate prediction of microstructural evolution during forging is essential for optimizing mechanical properties and process efficiency. Two commonly employed approaches for evaluating hot-deformation behavior are double-hit compression testing and processing maps. Double-hit experiments provide direct measurement of recrystallization kinetics through analysis of flow stress evolution during interrupted deformation, enabling quantitative assessment of microstructural restoration mechanisms. In contrast, process maps are widely used in the forging industry to identify favorable combinations of temperature and strain rate through analysis of power dissipation efficiency and flow stability. This work compares the predictive capabilities of these techniques using two distinct steel alloys with differing hot-deformation behaviors. Results from laboratory-scale testing are used to assess the relationship between recrystallization behavior measured through double-hit experiments and processing windows identified through process maps. The study will be validated by analyzing flow response and resulting microstructure on a series of large-scale demonstration forgings. |
