A strengthened article (and methods for making it) is provided that includes a glass, glass-ceramic or ceramic, having a plurality of primary surfaces, side edges, and a thickness. The article also includes a compressive stress region extending from one of the primary surfaces to a first selected depth in the article; a central region extending from a boundary located at a depth of 200 &#x3bc;m from the primary surfaces and the edges to the centroid of the article; and an outer region extending between the primary surfaces and edges to the boundary. Further, the maximum principal stress within the outer region is no more than two times the maximum principal stress within the central region. The primary surfaces and side edges may define a plurality of corners, and the corners may be defined by a chamfer, a fillet, or a curved shape.

A composite thermal barrier and methods of applying the composite thermal barrier to a metallic surface within a combustion chamber of an engine. The composite thermal barrier includes at least one metallic support structure, a metallic skin, and an insulation material. The metallic support structure is connected to a metallic surface within the combustion chamber of the engine. The metallic skin is disposed adjacent to the metallic support structure to define a void space between the metallic skin and the metallic surface. The insulation material is contained within the volume to form the composite thermal barrier.

A process using a three-piece mold for making a three-dimensionally shaped glass article having a flat area and a curved/bend area is disclosed. The process includes placing a glass sheet on a mold having a shaping surface with a desired surface profile for the shaped glass article including a flat area and a bend area, moving a flat area plunger toward the glass sheet to compress the glass sheet, heating a portion of the glass sheet corresponding to an area above the bend area of the mold to a temperature above a forming temperature, and moving a bend area plunger toward the heated glass sheet to compress the heated glass sheet. A temperature of the glass sheet in the area above the bend area of the mold is higher than a temperature of the glass sheet in the area above the flat area of the mold when compressing the heated glass sheet with the bend area plunger.

A stress reducing mounting for an electrolyte sheet assembly in a solid electrolyte fuel cell is provided that includes a support frame or manifold having an inner edge portion that supports a peripheral portion of the sheet assembly, a seal that affixes an edge of the peripheral portion to the frame or manifold, and a stress reducer disposed around the peripheral portion of the electrolyte sheet and the frame or manifold that reduces tensile stress in the peripheral portion of the electrolyte sheet when the peripheral portion is bent by pressure differentials or thermal differential expansion. The stress reducer is at least one of a convex curved surface on the inner edge portion of the frame or manifold that makes area contact with the peripheral portion when it bends in response to a pressure differential or thermal differential expansion, and a stiffening structure on the sheet peripheral portion that renders the ceramic sheet material forming the peripheral portion more resistant to bending. The stress reducing mounting reduces cracking in the electrolyte sheet at the peripheral portions due to tensile forces.
