Abstract


We studied liquid Zr46.5Ti18.2Cu7.5Ni10Be27.5 in the temperature range from 1060 K to 1255 K using a combination of quasielastic neutron scattering and newly developed electrostatic levitation. We show that not only the microscopic incoherent and coherent relaxation times, and the derived mean self-diffusion coefficient of Ni/Cu/Ti, but also the macroscopic melt viscosity exhibit very similar temperature dependences. Thus, independent of the experimental time/length scales and the different natures of the relaxation times, the Maxwell relation of linear viscoelasticity holds, as a result of highly coupled structural relaxation processes in the melt.
