Abstract Amorphous Ni-Ta was obtained by mechanically alloying pure crystalline powders of nickel and tantalum. Structural changes in the local atomic arrangement effected by the mechanical treatment were studied by X-ray scattering and EXAFS spectroscopy. Both X-ray scattering and EXAFS data represent the destruction of long-range order with increasing milling time, i.e., the crystalline-to-amorphous transition. In contrast to an EXAFS study on the Ni-Ti system, our analysis does not confirm the presence of chemical short-range order.
