WebIN792 were defined and tested. The alloys did not contain any Hf, since Hf promotes the formation of J/Jc-eutectic and hence lowers the incipient melting temperature. Furthermore, Hf causes mould reactions particularly at long casting cycles for large IGT-compo-nents.

WebThe oxidation behavior in air of a platinum containing nickel based superalloy (RJM2012) is compared with that of a similar alloy (IN792+Hf) without platinum. The distinct improvement in the oxidation resistance of the platinum containing alloy at high temperatures (1100°C) is explained in terms of the oxide morphologies and oxidation kinetics.
