Abstract
The results of investigations of pre-eutectic alloys of Cu–P–Sb system are presented. The melting temperature range 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 solidus and liquidus temperature. 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 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-phosphorus alloys is shown. 10 Ref., 2 Tables, 6 Figures.
Keywords: copper-phosphorus pre-eutectic alloys, antimony, temperature of solidus and liquidus, microstructure, ultimate tensile strength
