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.
WebDec 31, 1999 · Abstract: A series of directional solidification experiments have been conducted to elucidate the formation mechanism of eta and Cr-rich phases in the Ni-base superalloy IN792 + Hf. Both eta and Cr-rich phases were found to be the final solidification products developed from the remaining liquid after γ/γ′ eutectic reaction. WebDec 10, 2013 · Due to a good combination between the mechanical properties at the low/intermediate temperature regimes and the density, the alloy has found important applications in conventionally cast engine components, such as blades and rotors. This alloy has a high Ti + Al content, which contributes to a large volume fraction of the γ′ phase.
