Methods for chemically strengthening glass articles, e.g., glass sheets, are disclosed, in which computer-implemented techniques are employed to select the conditions, e.g., times, temperatures, and bath compositions and sizes, used in the chemical strengthening. The computer-implemented techniques can be applied to chemical-strengthening methods that employ more than one ion-diffusion treatment, e.g., more than one ion-exchange treatment or a combination of at least one ion-exchange treatment and at least one heat treatment. Through the use of the computer-implemented techniques, more precisely-controlled ion concentration profiles can be achieved in chemically-strengthened glass articles, which can improve the ultimate mechanical properties of the articles.
A method of chemically strengthening a glass article which comprises at least one mobile ion, the method comprising subjecting the glass article to one or more ion-diffusion processes in each of which the glass article is subject to a predetermined temperature versus time profile, wherein at least one profile is at least partially based on a computer-implemented model for the spatial distribution as a function of time of the at least one mobile ion within the glass article, said computer-implemented model comprising moving mobile ions within the glass article based on a random value, wherein the computer-implemented model discretizes at least part of the glass article into a plurality of layers internal to the glass article and at least one interface layer at an edge of the glass article;
