Abstract: A laminated glass article comprises a core layer comprising a core glass composition having an average core coefficient of thermal expansion (CTEcore) and a clad layer directly adjacent to the core layer and comprising a clad glass composition having an average clad coefficient of thermal expansion (CTEclad) that is less than the CTEcore such that the clad layer is in compression and the core layer is in tension. A compressive stress of the clad layer increases with increasing distance from the outer surface of the clad layer, transitions to a minimum tensile stress as a step-change at an interface region between the core layer and the clad layer, and a magnitude of the tensile stress increases continuously to a maximum tensile stress in the core layer. Other stress profiles, and methods of preparing laminated glass articles are also disclosed.

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.

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.
