Compressional and shear wave velocities of Zr{sub 46}Cu{sub 37.6}Ag{sub 8.4}Al{sub 8} bulk metallic glass (BMG) have been measured up to 6.3 GPa at room temperature using ultrasonic interferometry in conjunction with synchrotron X-radiography. The densities at high pressures are uniquely determined using the measured velocities. The experimental results for the elastic moduli of Zr{sub 46}Cu{sub 37.6}Ag{sub 8.4}Al{sub 8} show a reasonable agreement with the Voigt-Reuss-Hill approximation of the element metal phases, indicating that the elastic properties of the BMG have a close correlation with its constituent components.
