Abstract:
      The microstructure evolution and mechanical properties of powder metallurgy FGH96 alloy under different solution heat treatment conditions were analyzed by means of electronic probes, field emission scanning electron microscopy and other advanced detection methods. Results showed that the edge part of the powder metallurgy FGH96 alloy turbine disk was analyzed by electron probe. It was found that the bright white granular boride phase was observed, and the surface of the control element was scanned. It can be determined that the boride phase is mainly rich in elements W and Mo. As the solution temperature increased from 1080 °C to 1160 °C, both tensile strength and yield strength increased slightly, while tensile strength and yield strength increased with increasing cooling rate; FGH96 alloy after treatment with different solution temperature The creep performance is comparable, and as the cooling rate increases, the creep resistance is greatly increased. Through the research on the microstructure and mechanical properties of FGH96 alloy.
