ABSTRACT
The pressure-dependent acoustic velocities of a Pd[sub 39]Ni[sub 10]Cu[sub 30]P[sub 21] bulk metallic glass (BMG) have been measured up to 0.5 GPa by using an ultrasonic technique with the pulse echo overlap method. The elastic constants, the Debye temperature, and their pressure dependence are obtained. The isothermal equation of state (EOS) of the BMG is established in terms of the Murnaghan form. The atomic configurations of the BMG are discussed by comparing the elastic constants and the EOS with those of its metallic component and of other amorphous materials. © 2000 American Institute of Physics.
