| titleOfInvention | Nickel-based superalloys exhibiting minimal grain defects. |
| abstract | PROBLEM TO BE SOLVED: To provide a single crystal (SC) and directional solidification (DS) nickel-base superalloy exhibiting a minimum number of grain defects during casting. SOLUTION: A carbide-forming element is added to a nickel-base superalloy to minimize grain defects such as freckles and stray grain defects. Specifically, the addition of carbide forming elements generated from the liquid in the massy zone of the solidification interface of single crystal (SC) and directionally solidified (DS) nickel-based superalloys adds fleckles and stray grain defects in such alloys. Reduce the formation of A preferred nickel-base superalloy is about 6.00% to 9.25% tantalum by weight, about 4.7% by weight. 5% to 6.50% tungsten, about 2.75% or more rhenium, about 5.00% to 7.00% aluminum, About 0.10% or more of hafnium and an amount sufficient to form carbides with other components to significantly reduce freckle formation in the superalloy massy zone during casting (typically about 0.10 to 0.15%). Wt%) carbon. |
