A partial structure factor investigation of the bulk metallic glass Zr63Ni25Al12as studied by using a combination of anomalous X-ray scattering and reverse Monte Carlo modeling

A comparison between the resonant scattering curve obtained by anomalous small-angle X-ray scattering at the X-ray absorption edge of Ni and the complementary small-angle neutron scattering curve from an Al89Ni6La5alloy sample is reported. The sample does not comply with the two-phase approximation. The two resulting scattering curves are approximately proportional to each other in this particular case. The anomalous small-angle X-ray scattering resonant curve at the Ni absorption edge equals the Ni–Ni partial structure factor and, owing to the favourable neutron scattering lengths of Ni, La and Al, the neutron scattering curve is also proportional to that partial structure factor.

Abstract Anomalous X-ray Scattering experiments have been performed to study the local order in an amorphous CuZr sample prepared by mechanical alloying. The three partial structure factors were extracted both using a regularization algorithm to solve an ill-conditioned system of linear equations and applying the reverse Monte Carlo technique to the experimental data. Then the short range atomic distributions of similar samples prepared by different methods and investigated by different techniques are compared.

In this article, we show principles and advantages of anomalous x-ray scattering in combination with neutron scattering and reverse Monte Carlo modeling to characterize structures of non-crystalline materials, in particular, metallic glasses. Then, we briefly introduce examples of our recent applications to Pd40Ni40P20and Zr63Ni25Al12bulk metallic glasses having good glass-forming abilities.
