Patent number: 7361412Abstract: Self-propagating formation reactions in nanostructured multilayer foils provide rapid bursts of heat at room temperature and therefore can act as local heat sources to melt solder or braze layers and join materials. This reactive joining method provides very localized heating to the components and rapid cooling across the joint. The rapid cooling results in a very fine microstructure of the solder or braze material. The scale of the fine microstructure of the solder or braze material is dependant on cooling rate of the reactive joints which varies with geometries and properties of the foils and components. The microstructure of the solder or braze layer of the joints formed by melting solder in a furnace is much coarser due to the slow cooling rate. Reactive joints with finer solder or braze microstructure show higher shear strength compared with those made by conventional furnace joining with much coarser solder or braze microstructure.Type: GrantFiled: May 13, 2004Date of Patent: April 22, 2008Assignee: Johns Hopkins UniversityInventors: Jiaping Wang, Etienne Besnoin, Omar Knio, Timothy P.

Patent number: 6998180Abstract: A package is configured as a composite component with a substrate, at least one semiconductor component, and an enclosure, which are joined to one another. The heat-dissipating substrate is a single-layer or multilayer substrate with a thermal conductivity, transversely with respect to a joining surface to which the semiconductor component is joined, of greater than 170 W/m. The substrate may be a layered structure and/or a structure of graduated material composition, and it has an asymmetrical thermal expansion characteristic. By suitable selection the layers or the material graduation, it is possible to reduce and limit the shear distortion of the composite component formed of the substrate, the semiconductor component, and the enclosure.Type: GrantFiled: March 24, 2003Date of Patent: February 14, 2006Assignee: Plansee AktiengesellschaftInventors: Arndt Lüdtke, Heiko Wildner

Patent number: 6994920Abstract: A fusion welding method is provided for fusion welding at juxtaposed interface surfaces a first member, for example made of a first metal based on at least one of Ru, Rh, Pd, and Pt, with a second member made of a second metal, for example a high temperature alloy based on at least one of Fe, Co, and Ni, including at least one identified element, for example Al, that can form a continuous layer of a brittle intermetallic compound with the first metal that is free of such element. With the interface surfaces disposed in contact, energy is generated at the interface surfaces in a combination of an amount and for a first time selected to be sufficient to heat the interface surfaces to a fusion welding temperature. However, the first time is less than a second time that enables formation at the fusion welding temperature of the continuous layer of the brittle intermetallic compound at the interface surfaces.Type: GrantFiled: October 31, 2003Date of Patent: February 7, 2006Assignee: General Electric CompanyInventor: Gary Edward Trewiler

Patent number: 6974637Abstract: An article and TBC coating system thereon that in combination exhibit significantly improved spallation resistance. The article comprises a substrate formed of a metal alloy containing ruthenium and one or more refractory elements (e.g., tantalum, tungsten, molybdenum, rhenium, hafnium, etc.). The substrate is protected by a coating system comprising an aluminum-containing bond coat on the surface of the substrate and a ceramic coating bonded to the substrate by the bond coat. The bond coat, preferably an aluminide, is deposited so as to be substantially free of ruthenium, though ruthenium is present in the bond coat as a result of diffusion from the substrate into the bond coat.Type: GrantFiled: December 19, 2003Date of Patent: December 13, 2005Assignee: General Electric CompanyInventors: Jeffrey Allan Pfaendtner, Deborah A. Schorr, Ramgopal Darolia, Joseph David Rigney, Irene Spitsberg, William Scott Walston

Patent number: 6953627Abstract: A process for the production of thin walled parts of steel, wherein there are layers that are at least partly differently treatable relating to their strength and hardness qualities. This process can include creating a composite material from a plurality of different layers by connecting at least one core layer and at least one surface layer together. At least one layer of the core or surface layer is cast adjacent to another layer to form a composite material having an alloy gradient that is flat at each interface between any of the core layer or the surface layer. Next, the process can include deforming the composite material along a length of these layers. Finally the process can include heat treating the layers to transform the strength and hardness qualities of at least one of these layers.Type: GrantFiled: January 5, 2001Date of Patent: October 11, 2005Assignee: C.D.

Patent number: 6936353Abstract: Magnetic recording media having a magnetic layer with an easy magnetization axis lying about 45° out of plane of the magnetic layer is disclosed. SMNR from this media could be greatly improved from conventional longitudinal and perpendicular recording, because of an increase in the grain anisotropy that could be effectively written due to the angled recording configuration, resulting also in higher thermal stability, therefore, suitable for higher areal density recording.Type: GrantFiled: July 2, 2003Date of Patent: August 30, 2005Assignee: Seagate Technology LLCInventors: Zhong Stella Wu, Qixu David Chen, Samuel D.
