Patent number: 7854252Abstract: A castable high temperature aluminum alloy is cast by controlled solidification that combines composition design and solidification rate control to synergistically enhance the performance and versatility of the castable aluminum alloy for a wide range of elevated temperature applications. In one example, the aluminum alloy contains by weight approximately 1.0-20.0% of rare earth elements that contribute to the elevated temperature strength by forming a dispersion of insoluble particles via a eutectic microstructure. The aluminum alloy also includes approximately 0.1 to 15% by weight of minor alloy elements. Controlled solidification improves microstructural uniformity and refinement and provides the optimum structure and properties for the specific casting condition. The molten aluminum alloy is poured into an investment casing shell and lowered into a quenchant at a controlled rate.Type: GrantFiled: July 30, 2009Date of Patent: December 21, 2010Assignee: United Technologies CorporationInventors: Shihong Gary Song, Raymond C.

Patent number: 7655183Abstract: A durable Pd-based alloy is used for a H2-selective membrane in a hydrogen generator, as in the fuel processor of a fuel cell plant. The Pd-based alloy includes Cu as a binary element, and further includes “X”, where “X” comprises at least one metal from group “M” that is BCC and acts to stabilize the ? BCC phase for stability during operating temperatures. The metal from group “M” is selected from the group consisting of Fe, Cr, Nb, Ta, V, Mo, and W, with Nb and Ta being most preferred. “X” may further comprise at least one metal from a group “N” that is non-BCC, preferably FCC, that enhances other properties of the membrane, such as ductility. The metal from group “N” is selected from the group consisting of Ag, Au, Re, Ru, Rh, Y, Ce, Ni, Ir, Pt, Co, La and In. The at. % of Pd in the binary Pd—Cu alloy ranges from about 35 at. % to about 55 at. %, and the at. % of “X” in the higher order alloy, based on said binary alloy, is in the range of about 1 at. % to about 15 at. %.Type: GrantFiled: February 28, 2007Date of Patent: February 2, 2010Assignee: UTC Power CorporationInventors: Raymond C.
