Abstract: Chemically strengthened glass articles having at least one deep compressive layer extending from a surface of the article to a depth of at least about 45 μm within the article are provided. In one embodiment, the compressive stress profile includes a single linear segment extending from the surface to the depth of compression DOC. Alternatively, the compressive stress profile includes two linear portions: the first portion extending from the surface to a relatively shallow depth and having a steep slope; and a second portion extending from the shallow depth to the depth of compression. The strengthened glass has a 60% survival rate when dropped from a height of 80 cm in an inverted ball drop test and an equibiaxial flexural strength of at least 10 kgf as determined by abraded ring-on-ring testing. Methods of achieving such stress profiles are also described.

Abstract: Chemically strengthened glass articles having at least one deep compressive layer extending from a surface of the article to a depth of compression DOC of at least about 125 μm within the glass article. The compressive stress profile includes a single linear segment or portion extending from the surface to the depth of compression DOC. Alternatively, the compressive stress profile may include an additional portion extending from the surface to a relatively shallow depth and the linear portion extending from the shallow depth to the depth of compression.

Abstract: Embodiments are directed to strengthened glass articles comprising a thickness t≤1 mm (1000 μm), an inner region under a central tension CT (in MPa), and at least one compressive stress layer adjacent the inner region and extending within the strengthened glass article from a surface of the strengthened glass article to a depth of layer DOL (in μm), wherein the strengthened glass article is under a compressive stress at the surface CSs (in MPa), wherein the strengthened glass article is an alkali aluminosilicate glass article comprising 0-5 mol % Li2O, and at least 3 mol % Al2O3, and wherein the DOL≥70 μm, and a CSs/DOL ratio≥2.5 MPa/μm.

Abstract: Apparatus and methods for impact testing of a transparent substrate are provided. The apparatus includes a base (110) for receiving the transparent substrate (112), the base having a curved surface (124) about which the transparent substrate is bent by a first fixture (130) and a second fixture (132). An abrasive sheet (136) is disposed between the transparent substrate and an impacting object (138) which is released from above the substrate such that the force from the impacting object causes damage to the transparent substrate while the transparent substrate is bent about the curved surface.
