    Abstract: A non-frangible glass article strengthened by a dual or two-step ion exchange (IOX) process, where the first IOX step leads to a depth of compressive layer FSM_DOL>0.1·t or, in some embodiments, FSM_DOL>0.15·t, where t is the thickness of the glass, is provided. The glass article has a compressive stress CS1 after the first IOX step at the surface of from 100 MPa to 400 MPa or, in some embodiments, from 150 MPa to 300 MPa. The first IOX step is followed by a second IOX step, leading to a “spike” compressive stress CS2 after the second IOX step at the surface of greater than 500 MPa or, in some embodiments, 700 MPa. The width of the spike generated by the second IOX is between 1 μm and 30 μm, or between 8 μm and 15 μm, using the criteria where the magnitude (absolute value) of the slope of the spike is higher than 20 MPa/μm.

    Abstract translation: 通过双或两步离子交换（IOX）工艺加强的非易碎玻璃制品，其中第一IOX步骤导致压缩层的深度FSM_DOL> 0.1·t，或者在一些实施方案中为FSM_DOL> 0.15·t， 其中t是玻璃的厚度。 玻璃制品在表面的第一个IOX步骤之后的压应力CS1为100MPa至400MPa，或者在一些实施方案中为150MPa至300MPa。 第一个IOX步骤之后是第二个IOX步骤，导致在大于500MPa的表面处的第二个IOX步骤之后，或者在一些实施例中，700MPa，导致“尖峰”压缩应力CS2。 使用尖峰的斜率的大小（绝对值）高于20MPa /μm的标准，由第二IOX产生的尖峰的宽度在1μm至30μm之间或在8μm和15μm之间。
