Using ultrasonics, acoustic characteristics of Pd40Cu30P20, Zr55Cu30Al10Ni5, Zr65Pd12.5Ni10Al7.5Cu5, Cu55Zr30Ti10Pd5, Cu45Zr20Hf25Ag10 and Ti41.5Cu42.5Ni7.5Hf5Zr2.5Sn1 glassy alloys were examinedin terms of complex elasticity. The order of bulk modulus (K), Lamè parameter (λ ), Young (E ) andshear (G ) moduli of the glassy alloys is monopoltical character of glassy alloys, except for polymersand rubbers. For metals and alloys, ceramics, polymers and glassy alloys, Poison’s ratio correlateswell to ratio G /K. Complex elasticity indicates that viscoelasticity of the glassy alloys ispredominated by volumetric motion
