The Stokes–Einstein and Stokes–Einstein–Debye relations hold well in nonsupercooled liquids; however, sizeable deviations from the former appear in supercooled liquids, leading to a ‘‘decoupling’’ of translational diffusion from viscosity and reorientational relaxation. We attribute this breakdown and this ‘‘decoupling’’ to the existence of structured domains in the supercooled liquid. © 1995 American Institute of Physics.

    We investigate numerically the temperature and density dependence of the Stokes-Einstein ratio, Dη/T, and of two commonly-used variants thereof, Dτ and Dτ/T, where D is a diffusivity, η the shear viscosity, and τ a structural relaxation time. We consider a family of atomic...

    The Newtonian viscosity of the supercooled liquid measured by the continuous-strain-rate tensile test was investigated in the Pd[sub 40]Ni[sub 40]P[sub 20] metallic glass. It was found that continuous-strain-rate tests were applicable to determine the viscosity over a wide strain-rate region,...

    The initial stage of decomposition of a supercooled melt or a viscous liquid under heat-insulating conditions has been considered in terms of the method of virtual media. The heat removal from the interface is taken as the controlling process in the vicinity of a growing nucleus. In addition to...
