Research Abstract

Structural and compositional hetrogeneities in as-prepared and annealed Zr-based metallic glasses have been examined by developing anomalous small- and wide angle X-ray scattering (ASWAXS) methods. It has been demonstrated for the first time that the partitioning during quasicrystal formation plays an important role to understand the stability of the glass and the kinetics of (quasi) crystallization.
