Elastic constants and their pressure dependence of Zr41Ti14Cu12.5Ni9Be22.5C1 bulk metallic glass

The acoustic velocities and their pressure dependence of bulk Zr41Ti14Cu12. 5Ni9Be22.5C1 metallic glass (MG) have been measured up to 0.5 GPa by using a pulse echo overlap method. The elastic constants and thermodynamic parame ters as well as their pressure dependence of the MG have been determined. T he obtained elastic constants were compared to that of other kinds of glass es. More information about the microstructure, elastic properties, and glas s forming ability of the MG was obtained.
