Abstract

The atomic structure of the as-quenched Zr33Y27Al15Ni25 amorphous alloy which has double glass transition temperature was investigated by X-ray diffraction and compared with that of a sample heated at 773 K just above the second glass transition temperature Tg2 (772 K). The environmental structures around Zr, Y and Ni in both samples were determined by anomalous X-ray scattering (AXS) measurements at the K absorption edges of Zr, Y and Ni. On heating above Tg2, local ordering is developed around Y. However, no significant change was observed for ZrZr, ZrAl and ZrNi pairs.
