We discussed their physical properties, such as the thermal stability, the structure relaxation, the glass transition and the fragility , by constructing the structural model based on the three fundamental structures, i.e. the area (P) where the local atomic arrangements are similar with those of the crystals precipitated in the amorphous matrix, the area (I) consisting of densely packed icosahedral clusters, and the area (W) belonging to neither of them.
