Abstract
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.
