Abstract: Glass-based articles that include a compressive stress layer extending from a surface of the glass-based article to a depth of compression are formed by exposing glass-based substrates to water vapor containing environments. The glass-based substrates have compositions selected to avoid the formation of haze during the treatment process. The methods of forming the glass-based articles may include elevated pressures and/or multiple exposures to water vapor containing environments selected to avoid the formation of haze during the treatment process.

Abstract: A stack assembly is provided that includes a glass layer having a thickness, a first and second primary surface and a compressive stress region extending from the second primary surface to a first depth; and a second layer coupled to the second primary surface. The glass layer is characterized by: an absence of failure when the layer is held at a bend radius from about 3 to 20 mm, a puncture resistance of greater than about 1.5 kgf when the second primary surface is supported by (i) an ˜25 μm thick PSA and (ii) an ˜50 μm thick PET layer, and the first primary surface is loaded with a stainless steel pin having a flat bottom with a 200 μm diameter, a pencil hardness of at least 8H, and a neutral axis within the glass layer located between the second primary surface and half of the first thickness.

Abstract: A glass article comprising an alkali aluminosilicate glass that is formable by down-draw processes for example slot- and fusion-draw to thicknesses of 125 μm or less and is capable of being chemically strengthened by ion-exchange to achieve a compressive stress at its surface of at least 950 MPa, in some embodiments at least about 1000 MPa, and in other embodiments at least about 1100 MPa. The high surface compressive stress allows the glass to retain net compression and thus contain surface flaws when the glass is subjected to bending around a tight radius. The glass may be used in foldable display applications.
