Abstract

An analysis, based on the approach of crystallization statistics, is presented to describe crystallization on reheating a glass. The analysis treats heating carried out at the same or different rate relative to the cooling rate used to form the glass. The analysis takes account of the finite size of the critical nucleus and provides a description of the state of crystallinity in a body for both short and long times. The temperature of crystallization on reheating a glass is shown to depend strongly on the heating rate and on the barrier to crystal nucleation and less strongly on the cooling rate used to form the glass. For glasses with volume fractions crystallized greater than 10⁻⁹, the stability on subsequent heating increases with decreasing fraction crystallized at the glass transition.
