Patent number: 9556503Abstract: The disclosure provides a creep resistant alloy having an overall composition comprised of iron, chromium, molybdenum, carbon, manganese, silicon, nickel, vanadium, niobium, nitrogen, tungsten, cobalt, tantalum, boron, copper, and potentially additional elements. In an embodiment, the creep resistant alloy has a molybdenum equivalent Mo(eq) from 1.475 to 1.700 wt. % and a quantity (C+N) from 0.145 to 0.205. The overall composition ameliorates sources of microstructural instability such as coarsening of M23C6carbides and MX precipitates, and mitigates or eliminates Laves and Z-phase formation. A creep resistant martensitic steel may be fabricated by preparing a melt comprised of the overall composition followed by at least austenizing and tempering. The creep resistant alloy exhibits improved high-temperature creep strength in the temperature environment of around 650° C.Type: GrantFiled: September 30, 2015Date of Patent: January 31, 2017Assignee: U.S. Department of EnergyInventors: Jeffrey A.

Patent number: 9428825Abstract: One or more embodiments relates to a method of producing an MCrAlY bond coat comprising an MCrAlY layer in contact with a Y—Al2O3 layer. The MCrAlY layer is comprised of a ?-M solid solution, a ?-MAl intermetallic phase, and Y-type intermetallics. The Y—Al2O3 layer is comprised of Yttrium atoms coordinated with oxygen atoms comprising the Al2O3 lattice. The method comprises depositing an MCrAlY material on a substrate, applying an Y2O3 paste, and heating the substrate in a non-oxidizing atmosphere at a temperature between 400-1300° C. for a time sufficient to generate the Y—Al2O3 layer. Both the MCrAlY layer and the Y—Al2O3 layer have a substantial absence of Y2O3, YAG, and YAP phases.Type: GrantFiled: February 1, 2012Date of Patent: August 30, 2016Assignee: U.S. Department of EnergyInventors: Paul D.

The Y—Al2O3 layer is comprised of Yttrium atoms coordinated with oxygen atoms comprising the Al2O3 lattice. Both the MCrAlY layer and the Y—Al2O3 layer have a substantial absence of Y—Al oxides, providing advantage in the maintainability of the Yttrium reservoir within the MCrAlY bulk. The MCrAlY bond coat may be fabricated through application of a Y2O3 paste to an MCrAlY material, followed by heating in a non-oxidizing environment.Type: GrantFiled: October 29, 2013Date of Patent: April 21, 2015Assignee: U.S. Department of EnergyInventors: Paul D.
