Strengthened Silicate Glasses by Residual Stress: Depth of Compression and Surface Flaws Stability Conditions
Guglielmo Macrelli
The application of silicate glasses in severe service environments requires a precise evaluation of structural strength under mechanical loads and surface tribological conditions.…
Kinetic Flux Equations for Ion Exchange in Silicate Glasses
Guglielmo Macrelli
Ion exchange kinetic flux equations have been extensively investigated since the mid-twentieth century and continue to provide a fundamental framework for describing mass transport…
Diffusion in a two Phases System: Application to Ion Exchange in Silicate Glasses
Guglielmo Macrelli
Diffusion in a two-phase system is a classical problem discussed in the literature. The general solution of the one-dimensional case to this problem is revisited and a detailed der…
Thermodynamics and Kinetics of Silicate Glasses submitted to Binary Ion Exchange: Equilibrium Conditions and Interdiffusion Kinetics
Guglielmo Macrelli
Ion exchange processes between an ion reservoir and a solid matrix are modeled under the assumption that near interface volumes reach equilibrium in a much faster time than the ove…
Thermodynamic of Glass Indentation: Dissipative Aspects
Guglielmo Macrelli
A criterium is derived to understand the relevance of thermal effects resulting from high rate mechanical actions on glass surface. The criterium is based on the concept of charact…
Mathematical theory of diffusion in solids: solutions in the semi-infinite body and solution to a diffusion problem with a variable boundary condition
Guglielmo Macrelli
A review of solutions of solid-state diffusion problems in infinite and semi-infinite bodies is presented. Based on the identified solutions for the semi-infinite body a two-step d…
Ion exchange in silicate glass: mass average interdiffusion coefficient determination
Guglielmo Macrelli
The mass average interdiffusion coefficient DM is an approximated constant value of the interdiffusion coefficient which is relevant in the kinetics of ion exchange in silicate gla…
The Mathematical Theory Of Diffusion In Solids: Time Dependent First Kind Boundary Conditions
Guglielmo Macrelli
A new solution to the mono-dimensional diffusion equation for time-variable first kind boundary condition is presented where the time-variable function at the surface is derived pr…
Ion Exchange in Silicate Glasses: Physics of Ion Concentration, Residual Stress, and Refractive Index Profiles
Guglielmo Macrelli, Arun K. Varshneya, John C. Mauro
A systematic review of main physical effects generated by ion exchange in silicate glasses is presented. Ion concentration distributions, residual stress profiles, and refractive i…
