| Abstract Scope |
Nickel-based superalloys have been widely used to produce high performance components in advanced engine. In present research, isothermal compression tests of GH4065A Nickel-based superalloy were conducted at deformation temperatures of 1020-1140°C and strain rates of 0.001-1.0s-1. The deformation temperature and strain rate have a significant effect on the true stress-strain curves, from which the intrinsic connection between the flow stress and deformation behavior can be systematically studied. The apparent activation energy of deformation was calculated to be 454.5kJ/mol at the strain of 0.65 when the flow stress was steady. Meanwhile, the constitutive equation was constructed for modeling the hot plastic deformation of this superalloy. Based on the microstructure observation, the influence of hot processing parameters on microstructure has been deeply explored. Moreover, the microstructural mechanism during hot plastic deformation was revealed, which can provide the optimization of hot forging process for manufacturing high performance components in advanced engine. |
