摘      要：The longitudinal velocity Vl and shear velocity Vs of ultrasonic wave propagated along arbitrary three perpendicular directions of the Zr_(41.2)Ti_(13.8)Cu_(12.5)Ni_(10.0)Be_(22.5) bulk metallic glass(Zr/Ti BMG)have been measured at ambient pressure,under hydrostatic pressure(up to 0.5 GPa)and uniaxial compression(up to 70 MPa)using the pulse echo overlap *** third order elastic constants and the Grüneisen parameter related to the anharmonic properties were derived and *** was found that the BMG with marked different microstructural characteristics comparing with the amorphous carbon exhibited different behaviours related to shear vibratory under high pressure.
