The results of investigations of pre-eutectic alloys of the Cu – P – Sb system are presented. The melting temperature interval was determined using high-temperature differential thermal analysis. It was found that antimony alloying of copper-phosphorus pre-eutectic alloy provides a decrease in the temperature of solidus and liquidus. On the basis of experimental and literature data, the surfaces of liquidus and solidus of ternary alloys were constructed. Using micro-X-ray spectral analysis, the chemical composition and a number of structural components of the Cu - 6.29P - 1.97Sb alloy were determined. The influence of antimony on technological and mechanical properties, as well as morphology of cast ternary pre-eutectic copper-phosphorous alloys is shown. 10 Ref., 2 Tabl., 6 Fig.
Keywords: cupper-phosphorous pre-eutectic alloys, antimony, temperature of solidus and liquidus, microstructure, strength
