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.

Claims (9)

1. A gas turbine engine comprising:

a first blade outer air seal component;

a second blade outer air seal component adjacent the first blade outer air seal component; and

a seal comprising a W-seal body forming a first interface with the first blade outer air seal component and a second interface with the second blade outer air seal component,

wherein the W-seal body is formed from a sheet of a single crystal material, the sheet having a thickness within a range of 0.010 inches and 0.050 inches inclusive.

2. The gas turbine engine of claim 1 , wherein the seal is configured to accommodate operation within the engine at least at a temperature of 2000 degrees Fahrenheit.

3. The gas turbine engine of claim 1 , wherein the single crystal material has a <100> orientation.

4. The gas turbine engine of claim 1 , wherein the single crystal material has a <111> orientation.

5. The gas turbine engine of claim 1 , wherein the sheet has a thickness within a range of 0.010 inches and 0.015 inches inclusive.
