Non-equilibrium Thermodynamics: Structural Relaxation, Fictive temperature and Tool-Narayanaswamy phenomenology in Glasses

Starting from the second law of thermodynamics applied to an isolated system consisting of the system surrounded by an extremely large medium, we formulate a general non-equilibrium thermodynamic description of the system when it is out of equilibrium. We then apply it to study the structural relaxation in glasses and establish the phenomenology behind the concept of the fictive temperature and of the empirical Tool-Narayanaswamy equation on firmer theoretical foundation.Comment: 20 pages, 1 figur

Structural relaxation and their influence on glass transition temperature

Using of ,,StepScan" DSC method for measurement of structural relaxation and heat capacity

Glass Transition and Non-Isothermal Structrural Relaxation

The aim of present work is to compare the results of the glass transition temperature and DELTA Cp measurements obtained by conventional DSC with information acquired from stepwise DSC technique in the state of the thermal quasi-equilibrium
