The structural relaxation in a Zr 55 Cu 30 Ni 5 Al 10 bulk metallic glass was investigated by volume and enthalpy relaxation at various temperatures. The relaxation kinetics was well described by a stretched exponential relaxation function, UΓ°tΓ ΒΌ expΒ½ΓΓ°t=sΓ b . The Kohlrausch index, b, ranged from
The timescale of structural relaxation in a silicate melt defines the transition from liquid (relaxed) to glassy (unrelaxed) behavior. Structural relaxation in silicate melts can be described by a relaxation time, z, consistent with the observation that the timescales of both volume and shear relaxa
