WebJun 1, 2024 · The formation of Si-rich phase is induced by the rejection of Ti and Si into the residual liquid during the γ matrix formation. With the increase in Si content, the size distribution of (γ-γ′)... 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.
