Paper Abstract

Mechanical properties of glassy selenium and selenium based IR chalcogenide glasses Se55As45, Se67.5As20Ge12.5 and Se57I20As18Te3Sb2 were first studied using dynamical mechanical analysis (DMA). DMA method gave the valuable information about complex Young's modulus of the glassy materials. In parallel with the study of mechanical properties of pure Se and Se-based IR glasses there also has been cleared the character of the glass transition process. The results of DMA study were compared with data obtained by differential calorimetry. The glass transition temperature, established by calorimetric measurements is lower than the temperature, which corresponds to peaks of the loss tangent for all kinds of materials under study. Activation energies of relaxation processes in IR chalogenide glasses were calculated using DMA data.
