Chemical short-range order in liquid Al-Ni alloys.
The chemical short-range structure was studied in liquid Al-Ni alloys by x-ray absorption spectroscopy as a function of temperature and composition. A containerless technique, combining aerodynamic levitation and inductive heating, was used to position and melt the samples. The fluorescence yield x-ray absorption at the Ni K edge was measured by a multichannel solid-state Ge detector. The number of heteroatomic pairs around the scatterer is higher than for a homogeneous alloy.
