Effect of Deformation Temperation on Dynamic Recrystallization Behavior for High-Carbon Steel

Abstract:

Article Preview

Isothermal constant strain rate compression tests on high-carbon steel are carried out under deformation temperation of 850°C, 950°C, 1050°C、1150°C and 1250°C respectively and deformation of 0.7 using the THERMECMASTOR-Z thermal simulator at a strain rate of 1s-1. The austenite grain morphology before and after deformation and the true stress-strain curves during the deformation process are analyzed. The experimental results show that increased deformation temperation can obviously contribute to the grain refinement. And under the same strain rate conditions, as the deformation temperation rises, peak stress will move toward the opposite direction of strain increment,thus the dynamic recrystallization is apt to occur.
