Elastic moduli and behaviors of metallic glasses

We report apparent correlations among the elastic moduli, fracture strength, Vicker's hardness and glass transition temperature for various and available metallic glasses with marked different elastic and mechanical properties. In particular, an attempt is made to link the observed correlations with glass transition, relaxation and glass-forming ability. The clear correlations imply that the physical properties of glasses would be better controlled by selection of elements with suitable elastic moduli as constituents.
