Using ultrasonics, acoustic characteristics of Pd 40Cu 30P 20, Zr 55Cu 30Al 10N i5, Zr 65Pd 12.5Ni 10Al 7.5Cu 5, Cu 55Zr 30Ti 10Pd 5, Cu 45Zr 20Hf 25Ag 10 and Ti 41.5Cu 42.5Ni 7.5Hf 5Zr 2.5Sn 1 glassy alloys were examined in terms of complex elasticity. The order of bulk modulus (K), Lamé parameter (λ), Young (E) and shear (G) moduli of the glassy alloys shows the monopolistical character of the glassy alloys, except for polymers and rubbers. Poison's ratio correlates well to the anisotropy factor and the ratio G/K, accompanied by dilational and shear attenuation coefficients, showing characteristic one-dimensional elastic deformability of the glassy alloys. The complex elasticity shows that the viscoelasticity of the glassy alloys is predominated by volumetric motion, associated with the complex waves.
