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: A method of forming glass ceramic articles. The articles, in some embodiments, have a three dimensional shape. A fit mixture containing the glass ceramic in fit form and a glass fit are dispersed, in some embodiments, in a vehicle to create a slurry, which is then formed into a desired shape to make a green body. Forming may be accomplished by injection molding sinter forging, casting, casting and pressing, isostatically pressing, or the like. The green body is then fired at a high temperature to burn off the binder and fuse the glass ceramic and glass fit into a solid glass ceramic body. In some embodiments, the glass ceramic powder and glass fit material may be ion exchanged to achieve surface layers having high compressive stress, resulting in high damage resistance of the article.

Abstract: A glass sheet is formed on a mold into a glass article having a three-dimensional shape. The mold, with the glass article thereon, is arranged within an interior space of a radiation shield such that the mold is between a leading end barrier and a trailing end barrier of the radiation shield. The mold, glass article, and radiation shield are translated through a sequence of cooling stations while maintaining the mold between the leading and trailing end barriers, wherein the leading and trailing end barriers inhibit radiation heat transfer at leading and trailing ends of the mold.

Abstract: Ion-exchanged glass ceramic articles described herein have a stress that decreases with increasing distance according to a substantially linear function from a depth of about 0.07 t to a depth of about 0.26 t from the outer surface of the ion-exchanged glass ceramic article from a compressive stress to a tensile stress. The stress transitions from the compressive stress to the tensile stress at a depth of from about 0.18 t to about 0.25 t from the outer surface of the ion-exchanged glass ceramic article. An absolute value of a maximum compressive stress at the outer surface of the ion-exchanged glass article is from 1.8 to 2.2 times an absolute value of a maximum central tension (CT) of the ion-exchanged glass article, and the glass ceramic article has a fracture toughness of 1 MPa√m or more as measured according to the double cantilever beam method.
