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. WebMar 17, 2003 · For example, both Hf and Ti strongly segregate to the melt during solidification, and our previous work showed that the castability of IN792 could be improved significantly by control the concentration of such elements: adding ∼2wt.% Hf, or lowering Ti content resulted in crack free castings [6], [7].

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.
