Abstract

Glass transition phenomena for a fictive V2-VI3 compound have been described on the basis of fragmentation model in which glass materials begin to fragmentize at a certain temperature and the fragment size becomes small with increasing temperature. By a numerical calculation, the heating rate dependence of glass transition temperature was clearly presented, and fragment sizes at glass transition and melting temperature were estimated as 1.4μm and 20Å respectively. Further, thermodynamic aspects were discussed using the model and it was concluded that the glass transition is a sort of the first order transition.
