WebFeb 15, 2010 · The hot cracking deteriorates the mechanical properties of DS IN792 alloy although it can be decreased by controlling the concentrations of Ti, Ta, B, Zr and Hf [1], [2]. The conventionally cast (CC) process can improve or decrease greatly the tendency of hot cracking because of the refinement of grains and the effects of grain boundaries. WebDec 12, 2012 · The effect of solidification rate on the microstructure development of nickel-based superalloy under the temperature gradient of 500 K·cm−1 was studied. The results show that, with the increase of directional solidification rate from 50 to 800 μm·s−1, both the primary and the secondary dendrite arm spacings of the alloy decrease gradually, and the …

WebA 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. WebFeb 21, 2024 · IN939 was developed as an investment casting superalloy for use in gas turbine hot sections at temperatures up to 850°C, with emphasis on corrosion and oxidation resistance, while retaining excellent mechanical properties owing to precipitation strengthening by the γ ′ phase.
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.
