Abstract
Super-solvus heat treatment (SSHT) followed by quenching at different cooling rates was carried out for a new nickel-based powder metallurgy (PM) FGH98 superalloy, and the influence of various cooling rates on the microstructure including the grain boundary morphology and γ′ phases precipitation at the grain boundary or within the grains was studied systematically in this paper. The results showed that the grain boundaries were serrated with...
