Structure of Al83Cu17 eutectic melt doped with Ni

Structure of (Al_0.83Cu_0.17)_{1??? x} Ni _x liquid alloys has been studied at different temperatures by means of X-ray diffraction method. Structure factors and pair correlation functions are analysed. It is shown that the addition of Ni to Al_0.83Cu_0.17 eutectic melt results in the increase of chemical ordering in the topology of atomic distribution.
