Radial distribution functions for RE4Al3 metallic glasses (RE = Pr, Gd, Tb, Dy)

Abstract Using X-ray diffraction the radial distribution functions for RE 4 Al 3 (RE = Pr, Gd, Tb, Dy) metallic glasses have been determined. The RE-RE atomic distances and first coordination numbers have also been estimated. A structural model based on spherically arranged dense packed tetrahedra is proposed.
