Abstract

See full text

Glass-based articles comprise: a lithium-based aluminosilicate composition; a glass-based substrate having opposing first and second surfaces defining a substrate thickness (t), wherein t is less than or equal to 0.74 mm; and a stress profile comprising: a spike region extending from the first surface to a tail region. A stress profile comprises: a maximum compressive stress (CSmax) of greater than or equal to 450 MPa; a spike region extending from the first surface to a tail region; and the tail region extending to a center of the glass-based article; wherein the tail region comprises: a region of enhanced stress having a first average compressive stress (CSavg−1) of greater than or equal to 100 MPa; and a FSM depth of layer (DOLFSM) located at a depth of greater than or equal to 13 micrometers.
