摘要： Industrial applications of composites often require that the final product have a complex shape. In this invention intermetallic or ceramic phases are formed from sheets of unreacted elemental metals. The process described in this invention allows the final product shape be formed prior to the formation of the composite. This saves energy and allows formation of shaped articles of metal-intermetallic composites composed of brittle materials that cannot be deformed without breaking.

摘要： A method is disclosed for controlling a self-propagating reaction in a particulate medium. The method comprises controlling the boundary heat flux of the reaction to produce reaction waves which travel through the particulate medium undergoing a self-propagating reaction. The method provides a product having a unitary, solid structure with layers of alternating density. Preferably the reaction is a reaction between two metals to produce an intermetallic compound or between a metal and a non-metal to produce a ceramic compound. Nickel aluminide is a preferred intermetallic compound. Also disclosed is a controlled reactive sintering process for producing a finely divided intermetallic compound comprising comminuting the layered body of intermetallic compound. Also disclosed are a process for preparing an abrasive surface composed of a nickel aluminide binder and an abrasive material, an injection molding composition for preparing shaped articles of nickel aluminide, and a process for injection molding shaped nickel aluminide articles of greater than 98% theoretical density.

摘要： This invention relates to a method for producing components with internal architectures, and more particularly, this invention relates to a method for producing structures with microchannels via the use of diffusion bonding of stacked laminates. Specifically, the method involves weakly bonding a stack of laminates forming internal voids and channels with a first generally low uniaxial pressure and first temperature such that bonding at least between the asperites of opposing laminates occurs and pores are isolated in interfacial contact areas, followed by a second generally higher isostatic pressure and second temperature for final bonding. The method thereby allows fabrication of micro-channel devices such as heat exchangers, recuperators, heat-pumps, chemical separators, chemical reactors, fuel processing units, and combustors without limitation on the fin aspect ratio.

摘要： A method of applying a cerium diffusion coating to a preferred nickel base alloy substrate has been discovered. A cerium oxide paste containing a halide activator is applied to the polished substrate and then dried. The workpiece is heated in a non-oxidizing atmosphere to diffuse cerium into the substrate. After cooling, any remaining cerium oxide is removed. The resulting cerium diffusion coating on the nickel base substrate demonstrates improved resistance to oxidation. Cerium coated alloys are particularly useful as components in a solid oxide fuel cell (SOFC).
