AbstractBy using small-angle x-ray scattering technique, correlation lengths of the density fluctuation are determined for the bulk metallic glass Zr41.2Ti13.8Cu12.5Ni10Be22.5 around the glass transition temperature T-g. Nanoscale inhomogeneities were found to exist in the supercooled liquid and glass state. The correlation length was found to vary with temperature T in an exponential law delta(T) = delta(0) + A(1) exp[-(T - T-infinity)/T-1], where T-infinity is the Vogel temperature, and parameters delta(0), A(1) and T-1 were simulated to be 16.45 nm, 1.88 x 10(29) nm, and 9.65 K, respectively, in the temperature region from T-g to T-g + 80 K. The correlation length of the density fluctuation obtained by the small-angle x-ray scattering method can be considered as the characteristic length of glass transition.
