The type of atomic distribution in Cd-Al-Sn liquid eutectic alloys

This work presents the results of an x-ray scattering investigation of the short-range order in cadmium-aluminum-tin alloy at the eutectic concentration for a wide interval of temperatures. From the experimental x-ray scattering curves obtained for this sample, a Minsk-22 computer was used to calculate the atomic distribution for different temperatures. According to the analysis of the curves of the scattered x-ray intensity and the atomic distribution curves, it has been established that the eutectic Cd-Al-Sn alloy in the region of complete melting is characterized by a “quasieutectic” distribution of the atoms of the pure components.
