Study of thermo-mechanical properties in glassy Se and Se98M2 (M=In, Sb and Sn) alloys

• Metal-induced effects on thermo-mechanical properties of glassy Se have been studied.
• Thermo-mechanical properties are varied significantly after incorporation of In, Sn and Sb additives.
• A correlation between Mohs-hardness and micro-harness of present glasses has been observed.

The present work investigates the influence of additives (In, Sb and Sn) on the micro-hardness and related thermo-mechanical properties of glassy Selenium. The results indicate that micro-hardness of Se is changed significantly after the incorporation of In, Sb and Sn additives. Some other useful thermo-mechanical parameters like volume (Vh) and formation energy (Eh) of micro-voids in the glassy network and the modulus of elasticity E are also calculated for present glasses.
