Hf lowers the incipient melting temperature of superalloy. As carbon content in Hf-bearing alloy decreases, the incipient melting temperature drops furthey. PD ingots have stronger tendency to incipient melting than HRS ones. Even though in PD ingot, the sensitivities at both ends of the ingot are q...

The microstructure changed markedly with increasing solution temperature, i.e eutectic γ' phases and coarse primary γ' phase are redissolved continuously into matrix, which was finished at 1250-1260℃, and more and finer γ' phases are reprecipitated. The grain boundary morphology changed gradually to...
