Influence of experimental conditions on enthalpy relaxation observed by cyclic measurement with constant heating rate

• Fast study by cyclic DSC experiments with constant heating rate
• Fictive temperature for high cooling rates depends on heating rate used.
• TNM parameters from numerical fitting are not affected by heating rate.

The cyclic experiments with constant heating rate following cooling by various cooling rates were done using DSC to be able to apply different methods of estimation of TNM model parameters. The advantage and limitation of employed experimental procedure is discussed and the composition of (GeS2)y(Sb2S3)1 − y glasses for y = 0.2 and 0.3 was used as model systems.
