摘要：

The microstructure evolution and mechanical properties of powder metallurgy FGH96 alloy under different solution heat treatment conditions were analyzed by electronic probes, field emission scanning electron microscopy and other advanced detection methods. The results show that bright white granular boride phase is observed in the edge of the powder metallurgy FGH96 alloy turbine disk by electron probe. According to the scanning results of the control element, it can be ascertained that the boride phase is mainly rich in elements W and Mo. As the solution temperature increases from 1080 to 1160 degrees C, both tensile strength and yield strength increase slightly, and they increase with increasing cooling rate. FGH96 alloy after the treatment with different solution temperatures exhibits comparable creep performance; however, as the cooling rate increases, the creep resistance is greatly increased.
