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.
Claims9
A method for forming a seal configured to interface with at least a first component and a second component of a gas turbine engine, the method comprising:
- obtaining an ingot, the obtained ingot including a powder material, or a cast material, or a columnar grained material 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,
- wherein the sheet has a thickness within a range of 0.01 inches and 0.05 inches inclusive, and
- wherein the processing of the ingot includes applying a rolling technique.
