Abstract: A laminated glass article comprises a core layer comprising a core glass composition, and a cladding layer directly adjacent to the core layer and comprising a clad glass composition. A stress of the cladding layer increases with increasing distance from an outer surface of the cladding layer from a compressive stress to a tensile stress, transitions to a compressive stress as a step-change at an interface region between the core layer and the cladding layer, and increases with increasing distance from the interface region to a center of the core layer from the compressive stress to a tensile stress.

Abstract: A laminated glass article includes a core layer and a clad layer directly adjacent to the core layer. The core layer is formed from a core glass composition. The clad layer is formed from a clad glass composition. An average clad coefficient of thermal expansion (CTE) is less than an average core CTE such that the clad layer is in compression and the core layer is in tension. A compressive stress of the clad layer decreases with increasing distance from an outer surface of the clad layer within an outer portion of the clad layer and remains substantially constant with increasing distance from the outer surface of the clad layer within an intermediate portion of the clad layer disposed between the outer portion and the core layer. A thickness of the intermediate portion of the clad layer is at least about 82% of a thickness of the clad layer,

Abstract: Glass-based articles comprise stress profiles providing improved drop performance. A glass-based substrate comprises: a glass transition temperature (Tg), a liquid fragility index (m), and fictive temperature (Tf), wherein Tg is less than or equal to 650° C., a value of Tf minus Tg is greater than or equal to −30° C., and m is greater than or equal to 25. A stress relaxation rate is greater than or equal to 10%, or 20% or more. The articles can comprise a lithium-based aluminosilicate composition and a fracture toughness that is greater than or equal to 0.75 MPa*m0.5. The stress profiles comprise: a spike region extending from the first surface to a knee; and a tail region extending from the knee to a center of the glass-based article, the tail region comprising: a negative curvature region wherein a second derivative of stress as a function of depth is negative; a depth of compression (DOC) that is greater than or equal to 0.22t, and a parabolic region originating at the DOC and extending to the center of the glass-based article.

Abstract: Methods for compensating for warp typically exhibited by glass-based articles having non-uniform thicknesses as a result of ion exchange strengthening are provided. The methods include producing a molding surface of a mold based on a measurement of warp obtained by a specified ion exchange strengthening of a glass-based substrate of non-uniform thickness, such that the molding surface offsets the warp. Glass-based substrates resulting from the mold can then be exposed to the specified ion exchange strengthening and form glass-based articles that are substantially free of warp.

Abstract: A transparent article is described herein that includes: a glass-ceramic substrate comprising first and second primary surfaces opposing one another and a crystallinity of at least 40% by weight; and an optical film structure disposed on the first primary surface. The optical film structure comprises a plurality of alternating high refractive index (RI) and low RI layers and a scratch-resistant layer. The article also exhibits an average photopic transmittance of greater than 80% and a maximum hardness of greater than 10 GPa, as measured by a Berkovich Hardness Test over an indentation depth range from about 100 nm to about 500 nm. The glass-ceramic substrate comprises an elastic modulus of greater than 85 GPa and a fracture toughness of greater than 0.8 MPa·√m. Further, the optical film structure exhibits a residual compressive stress of ≥700 MPa and an elastic modulus of ≥140 GPa.

Abstract: A glass substrate comprises: a first position, wherein a tensile stress of the glass substrate is insufficient to cause fragmentation of the glass substrate into small pieces upon fracture of the glass substrate; and a second position, wherein the glass substrate is bent relative to the first position, and wherein the tensile stress of the glass substrate is sufficient to cause fragmentation of the glass substrate into small pieces upon fracture of the glass substrate. The glass substrate can include a first surface and a second surface. In the first position, the first surface and the second surface of the glass substrate can be planar. In the second position, the first surface and the second surface of the glass substrate can be planar. The small pieces can be generally cubic. In the second position, the glass substrate can be bent uniaxially along a bend axis of the glass substrate.
