Abstract
Thermal elasticity of two kinds of bonding-type glassy alloys, Zr55Cu30Al10Ni5 and Pd40Cu30Ni10P20, during progressive devitrification was evaluated by Poisson’s ratio, Debye temperature, and internal frictions in terms of topological change in metallic clusters. Both alloys showed opposite behavior for thermal elasticity: thermal softening associated with relaxation of icosahedral clusters and thermal-induced entropy elasticity associated with the rotational and vibrational motions of polyhedral clusters, and an increment of internal friction based on electron-longitudinal phonon interaction derived from the variation amount of potential energy among atoms, showing vanishment of free electrons.
