    Abstract: Methods for creating a cast component, along with the resulting cast components, are provided. The method may include heating a mold having a cavity therein; supplying a first molten metal material into the cavity of the mold such that the first molten metal material is directed to a first portion of the cavity of the mold; supplying a second molten metal material into the cavity of the mold such that the second molten metal material is directed to a second portion of the cavity of the mold, wherein the first molten metal material is compositionally different than the second molten metal material; and thereafter, allowing the first molten metal material and the second molten metal material to form the cast component.

    Abstract: A method and apparatus for minimizing engine weight for a turbine engine by utilizing one or more discrete protuberances disposed on an engine component wall. The wall can have a nominal thickness to decrease engine weight while the protuberances can provide increased discrete thicknesses for providing one or more cooling holes. The increased thickness at the protuberances provides for an increased thickness to provide sufficient length to increase cooling hole effectiveness.

    Abstract: A method of fabricating an object is provided. The method includes depositing a first material between second material such that the second material is at opposite sides of the first material, the first material forming a metal, ceramic, or metal-ceramic. The second material is selectively removable from the first material to reveal sidewalls of the first material so that the first material has a more uniform vertical profile than would be the case if the first material was deposited without the second material.

    Abstract: A nickel-based superalloy is provided, which includes: 5.6 wt % to 6.6 wt % aluminum; 6.0 wt % to 9.0 wt % tantalum; 4.0 wt % to 7.0 wt % chromium; 4.0 wt % to 7.0 wt % tungsten; 0.5 wt % to 2.5 wt % molybdenum; 1.5 wt % to 5.5 wt % rhenium; 7.0 wt % to 13.0 wt % cobalt; 0.1 wt % to 0.7 wt % hafnium; 0.001 wt % to 0.005 wt % carbon; 0.002 wt % to 0.05 wt % boron; up to 0.1 wt % yttrium; and a balance of nickel and incidental impurities, wherein the composition exhibits a rupture life that is greater than 80 hours at 1093.3° C. and 20 ksi and an oxidation resistance of less than 25.4 μm surface loss at 1176.7° C. after a 400 hour Mach I test. Components are also provided formed from such a nickel-based superalloy.
