Analysis of Worm Deformation Behavior of GH2132 Superalloy

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