Analysis of Worm Deformation Behavior of GH2132 Superalloy

Abstract GH2132 superalloy performances excellent properties, such as the good rupture strength and yield strength below 923K, the fine processing plasticity and the good welding properties. The warm working behavior of GH2132 superalloy at 673 K – 773K is investigated by a thermal simulator in this paper. The results show that the worm working effects at the center of specimen is the most significant compared with other positions. The deformation temperature and strain rate is the key parameters significantly affecting the warm working behavior. The increase of the temperature enhances the recovery softening effect, which reduces the stress and the work hardening effect slightly. The deformation heat is significant with the increasing strain rate, which results in the work hardening behavior does not change markedly. This study provides an important reference for the worm forming of GH2132 superalloy.
