Abstract: An article comprising an ion-exchanged glass material that prevents sharp contact flaws from entering a central region of the material that is under central tension and thus causing failure of the material. The glass material may be a glass or glass ceramic having a surface layer under compression. In some embodiments, the depth of the compressive layer is greater than about 75 μm. The greater depth of layer prevents flaws from penetrating the compressive layer to the region under tension.

Abstract: Embodiments of alkali aluminosilicate glass articles that may be chemically strengthened to achieve a maximum surface compressive stress that exceeds compressive stresses that have been achieved in similar glasses are disclosed. In one or more embodiments, the fictive temperature of these glass articles may be equal to the 1011 poise (P) viscosity temperature of the glass article. In some embodiments, the strengthened alkali aluminosilicate glass articles described herein may exhibit a maximum compressive stress of at least about 400 MPa, 800 MPa, 930 MPa or 1050 MPa. In some embodiments, the strengthened alkali aluminosilicate glass articles described herein may exhibit a compressive stress layer extending to a depth of layer of at least about 40 μm (in samples having a thickness of 1 mm). In still other embodiments, these strengthened alkali aluminosilicate glass articles exhibit a parabolic or near-parabolic tensile stress profile in the central region of the glass articles.

Abstract: A cover element for a foldable electronic device that includes a foldable glass element, first and second primary surfaces, and a compressive stress region extending from the first primary surface to a first depth that is defined by a stress σI of at least about 100 MPa in compression at the first primary surface. The device also includes a polymeric layer disposed over the first primary surface. The glass element has a stress profile such that when the glass element is bent to a target bend radius of from 1 mm to 20 mm, to induce a bending stress σB at the first primary surface in tension, σI+σB

Abstract: Embodiments of a method for pair bending glass articles is provided herein. In the method, a first glass article and a second glass article are stacked to form a stack. The first glass article includes a first surface, a second surface that opposes the first surface, and a first composition having first annealing and softening temperatures. The second glass article includes a third surface, a fourth surface that opposes the third surface, and a second composition having second annealing and softening temperatures. The annealing temperatures are within 35° C. of each other and are at least 550° C. The softening temperatures are within 35° C. of each other and are at least 750° C. In the method, the stack is placed on a mold, and the stack is heated to a sagging temperature such that a shaped stack is formed.
