Abstract:

Superalloy GH4169 as one of high temperature structural material is widely used in aviation industry. Isothermal compression of superalloy GH4169 has been conducted on Gleebe-1500D hot simulation at the deformation temperatures ranging from 950°C to 1100°C,the strain rates ranging from 0.01s-1 to 10s-1, and the height reduction of 50%. Effect of processing parameters ,i.e. deformation temperature, strain rate and strain, on the hot deformation behaviors of superalloy GH4169 was studied. The research shows that the fine dynamic recystallization grains could be obtained at the condition of high deformation temperature and low strain rate. Constitutive equation of superalloy GH4169 was established by experimental data. Error analysis showed that calculated stress values by the established constitutive equation were coincident with experimental data well, and it provided the theory basis to optimize forging processing of superalloy GH4169.
