Abstract: 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 μm 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.

Abstract: Glass articles comprising an outer region extending from an outer surface of the glass article to a depth of layer and methods of making the same are described. The outer region is bounded by at least one edge of the glass article and is under an intrinsic neutral stress or an intrinsic compressive stress. A core region of the glass article is under a tensile stress. A compressive element applies an external compressive stress to the at least one edge and increases the intrinsic stress on the outer region and reduces the tensile stress in the core region of the glass article. The glass article may be a strengthened glass article such that the outer region is under compressive stress, and the external compressive stress applied by the compressive element has a magnitude such that the glass article has an overall internal stress defined by: ∫0tσdt≠0 where t is a thickness of the glass article and σ is the internal stress.

Abstract: A method of making articles from preformed materials includes placing a preformed material on a mold such that a non-quality region of the preformed material contacts the mold and a quality region of the preformed material is free of contact with the mold. A non-contact support is provided to the quality region to control sagging of the quality region. A reformable area of the preformed material is formed into a select shape by contacting the reformable area with a forming tool while restricting contact between the forming tool and the reformable area to the non-quality region. After the forming of the reformable area, an article is extracted from the quality region.

Abstract: 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.

Abstract: Making a glass-based article having a coating and a target shape which comprises a planar central portion and a perimeter portion which borders at least part of the planar central portion and extends out of the plane of the planar central portion, the perimeter portion having a perimeter edge and a target edge-to-opposite edge dimension. The method includes forming a glass-based part to provide an initial formed part having an initial three-dimensional shape that is different from the target shape for at least the target edge-to-opposite edge dimension. Applying a coating to the initial formed part to form the glass-based article having a coating, the coating imparting a stress to the initial molded part that causes a calculated, warp-induced change to the initial shape.
