    Abstract: A method of manufacturing includes providing a casting assembly, providing a material having solid, transition, and liquid phases, heating the material to form the liquid phase, supplying the material to the casting assembly, cooling the material, monitoring the solidification of the material from the liquid phase through the transition phase, and moving one of the casting mold or the reusable core in a first direction relative to the other when a substantial portion of the reusable core contacts the transition phase. The casting assembly comprises a casting mold and a reusable core inserted within the casting mold.

    Abstract: Aspects are directed to a tribological and creep resistant system configured to operate at temperature in excess of 750° C., comprising: a piston seal that includes a nickel base alloy, where the nickel base alloy includes a Ni3(Al,X) type precipitated phase in an amount greater than 40% by volume. Aspects are directed to a system comprising: a piston seal that includes a cobalt-based alloy. Aspects are directed to a method comprising: heat treating an ingot of a nickel base alloy that includes coarsening a precipitated phase to facilitate forging or wrought forming the ingot, machining the ingot to include a substantially flat surface, and processing the ingot to generate a piston seal.

    Abstract: A gas turbine engine includes a rotor that has a rotor disk and a plurality of circumferentially-spaced blades. The rotor disk and the blades are co-rotatable about an axis. A case circumscribes the rotor. The rotor disk is tuned, with regard to centrifugal and thermal growth responsiveness, to the case for a given operational scenario of the gas turbine engine such that the rotor disk and case together provide a tuned clearance response. The operational scenario involves a series of engine events that include at least two of engine acceleration, engine deceleration, engine steady-state operation.

    Abstract: A process includes solution heat treating a nickel based superalloy with greater than about 40% by volume of gamma prime precipitate to dissolve the gamma prime precipitate in the nickel based superalloy; cooling the nickel based superalloy to about 85% of a solution temperature measured on an absolute scale to coarsen the gamma prime precipitate such that a precipitate structure is greater than about 0.7 micron size; and wrought processing the nickel based superalloy at a temperature below a recrystallization temperature of the nickel based superalloy. A material includes a nickel based superalloy with greater than about 40% by volume of gamma prime precipitate in which the precipitate structure is greater than about 0.7 micron size.

    Abstract: Aspects of the disclosure are directed to a seal configured to interface with at least a first component and a second component of a gas turbine engine. A method for forming the seal includes obtaining an ingot of a fine grained, or a coarse grained, or a columnar grained or a single crystal material from a precipitation hardened nickel base superalloy containing at least 40% by volume of the precipitate of the form Ni3(Al, X), where X is a metallic or refractory element, and processing the ingot to generate a sheet of the material, where the sheet has a thickness within a range of 0.010 inches and 0.050 inches inclusive.
