抄録

Using ultrasonics, acoustic characteristics of Pd40Cu 30P20, Zr55Cu30Al10N 15, Zr65Pd12.5Ni10Al7.5 Cu5, Cu55Zr30Ti10Pd5, Cu45Zr20Hf25Ag10and Ti 41.5Cu42.5Ni7.5Hf5Zr 2.5Sn1 glassy alloys were examined in terms of complex elasticity. The order of bulk modulus (K), Lamè parameter (λ), Young (E) and shear (G ) moduli of the glassy alloys is monopoltical character of glassy alloys, except for polymers and rubbers. For metals and alloys, ceramics, polymers and glassy alloys, Poison's ratio correlates well to ratio G/K. Complex elasticity indicates that viscoelasticity of the glassy alloys is predominated by volumetric motion.
