Abstract

We propose a unified routine to determine the enthalpic fictive temperature of a glass with arbitrary thermal
history under isobaric conditions. The technique is validated both experimentally and numerically using a
novel approach for modeling of glass relaxation behavior. The technique is applicable to glasses of any thermal
history, as proved through a series of numerical simulations where the enthalpic fictive temperature is
precisely known within the model. Also, we demonstrate that the enthalpic fictive temperature of a glass can
be determined at any calorimetric scan rate in excellent agreement with modeled values.
