Numerical Simulation of Hot Forging For the Disc of Superalloy GH4169

摘要：

In this paper, the hot deformation behavior of GH4169 superalloy were investigated at temperature of 9001020℃ and at strain rate of 0.001-0. Is-1 up to a 60％ height reduction of the sample using isothermal constant strain rate compression tests on process annealed material. The high temperature deformation behaviour of pure titanium was characterized based on an analysis of the stress-strain curves The proposed constitutive equation and the stress-strain curves were implanted into DEFORM2D, a hot forging process for the disc of GH4169 was simulated, and the micro-variable, recrystallized volume fraction, average grain size, recrystallized grain size and etc., were plotted with a contoured figure. According to the comparision between the experimental and predicted result, the absolute error between them is acceptable. The method for microstructure prediction will be significant to the engineering.
