high entropy alloys, solid solution, structure factors, short range order


X-ray diffraction method has been carried out to study the structure in the equiatomic InPbGaSnCu high entropy alloy in liquid state. Structure factors and pair correlation functions have been analyzed and used to determine the main structure parameters. Existence of shoulder on right hand side of principal peak and its transformation was the main feature of structure factors. Comparison of structure functions and main parameters obtained from them for multicomponent alloy with ones for constituent elements shown that mixing process is related with formation of structural inhomogeneities in liquid state.
