Resum
The temperature dependence of the relaxation times of Cu46Zr46Al8 glass was measured by means of mechanical spectroscopy and static stress-relaxation measurements. The weak intensity of secondary relaxation in this alloy allows us to correlate the characteristic times of dynamic and static measurements of primary relaxation. The glassy dynamics of an isoconfigurational state are found to follow an Adam-Gibbs-Vogel expression with the glassy state defined by a fictive temperature. The combination...
