Summary

INTERNAL FRICTION MEASUREMENTS ARE USED TO DETERMINE THE CONDITIONS OF FORMATION AND STABILITY OF VITREOUS PHASE OBTAINED AFTER THE QUENCHING OF WATER-GLYCEROL SOLUTIONS. THE SPECTRA INTERNAL FRICTION VERSUS TEMPERATURE EXHIBIT NEAR 193 K, A PEAK WHICH HAS BEEN ATTRIBUTED TO THE GLASS TRANSITION OF THE VITREOUS PHASE DISPERSED WITHIN THE CRYSTALLINE MATRIX. AFTER ISOTHERMAL ANNEALINGS, THE AMPLITUDE OF THIS PEAK DECREASES SINCE WATER CONTAINED IN THE VITREOUS PHASE IS CRYSTALLIZED. SO, THE TIME-TEMPERATURE-TRANSFORMATION DIAGRAM CAN BE ESTABLISHED BY THE DETERMINATION OF CRYSTALLIZATION KINETICS.
