    Abstract: Ion exchangeable glasses having coefficients of thermal expansion (CTE) at least about 90×10−7° C.−1. The glasses undergo rapid ion exchange, for example, in a molten KNO3 salt bath to a depth of layer of greater than 30 microns in less than 2 hours at temperatures of 370° C. to 390° C. When ion-exchanged to a depth of layer between 30 to 50 microns, the glasses exhibit a Vickers median/radial crack initiation threshold exceeding 30 kilograms force (kgf). The glasses are fusion formable and, in some embodiments, compatible with zircon.

    Abstract: Embodiments of this disclosure pertain to glass articles that comprise a maximum CS magnitude (CSmax) of about 900 MPa or greater, a CS magnitude of 750 MPa or greater at a depth of about 5 micrometers, and a maximum CT magnitude (CTmax) disposed at a depth from the first major surface in a range from about 0.25 t to about 0.75 t. Embodiments of a curved glass article are also disclosed. In one or more embodiments, such curved glass articles include the first major concave surface comprising a maximum radius of curvature of about 100 mm or greater and a first maximum CS value (CSmax1) of greater than about 800 MPa, a second major convex surface comprising a second maximum CS value (CSmax2), wherein the CSmax2 is less than CSmax1. Embodiments of an automotive interior system including such curved glass articles and methods of making glass articles are also disclosed.

    Abstract: An alkali aluminosilicate glass that can be chemically strengthened and formed into a three dimensional shape. The glass has a softening point of less than about 825° C. and a high temperature coefficient of thermal expansion of less than about 30 parts per million (ppm)/° C. The glass may be ion exchanged after the three dimensional shape is formed. When ion exchanged, the glass has a surface layer that is under a compressive stress of at least about 700 MPa.
