摘要：

FGH 95 is a powder metallurgy (P/M) processed superalloy, which was developed in the 1980s in China. One of the applications of FGH 95 was for high pressure turbine blade retainers. The manufacturing processes used to produce FGH 95 blade retainers consisted of atomization by plasma rotating electrode process (PREP), hot isostatic pressing (HIP) at super-solvus temperature and a heat treatment with sub-solvus solution. The material had an equiaxed grain structure (ASTM 6.5-7.5) with a fine dispersion of gamma prime and MC carbide precipitates. Statistics of the mechanical properties data from batch production of the FGH 95 blade retainers were investigated. The As-HIP FGH 95 blade retainers showed high strength at room temperature and 650 degrees C, excellent creep resistance and outstanding stress rupture strength at 650 degrees C.
