摘要：

Heat extraction behaviors of a FGH96 P/M superalloy disk under static air cooling, forced air cooling and oil quenching conditions were studied by experiments and the surface heat transfer coefficients were obtained by solving the inverse thermal problems. Numerical simulation of the heat-treatment process of a real disk was then carried out. The results showed that the heat extraction rates of oil quenching were much higher than those in the other two conditions, and the peak value was almost 10 times of that in the static air cooling. The heat-treatment process was appropriate as the stress generated in the quenching process was lower than the yield strength of the disk material.
