Patent number: 7722731Abstract: A method for utilizing plastic deformation resulting from grain boundary sliding with or without a novel joint compound that leads to the joining of advanced ceramic materials, intermetallics, and cermets. A joint formed by this approach is as strong as or stronger than the materials joined. The method does not require elaborate surface preparation or application techniques. The method also allows for the formation of transparent joints between two subunits of a construct joined via plastic deformation. The method can be used to tailor residual stresses and maintain native porosity.Type: GrantFiled: December 12, 2006Date of Patent: May 25, 2010Assignee: UChicago Argonne, LLCInventors: Jules L.

Patent number: 6843960Abstract: A method for preparing compositionally graded metallic plates and compositionally graded metallic plates suitable for use as interconnects for solid oxide fuel cells are provided. The method of the invention, utilizing powder metallurgy, enables making metallic plates of generally any desired composition to meet the corrosion requirements of fuel cells and other applications, and enables making metallic plates of graded composition from one surface of the plate to the other. A powder of the desired alloy composition is obtained, then solvents, dispersants, a plasticizer and an organic binder are added to form a slip. The slip is then formed into a layer on a desired substrate that can be flat or textured. Once dried, the layer is removed from the substrate and the binder is burned out. The layer is sintered in a reducing atmosphere at a set temperature for a predefined duration specific to the materials used and the desired final properties.Type: GrantFiled: June 12, 2002Date of Patent: January 18, 2005Assignee: The University of ChicagoInventors: Michael Krumpelt, Terry Alan Cruse, John David Carter, Jules L.
