Abstract
The effect of impurities on the structural and physicochemical properties of melts is considered in order to improve the service properties of cast high-temperature alloys. The changes in the state of nickel melts depending on the tin impurity content and the temperature are studied using the parameters of such structurally sensitive properties as density and surface tension. When the tin content in nickel melts increases to several hundredths of a percent, their density and compression effect are found to increase; however, a further increase in the tin content to 0.6 wt % is accompanied by a significant decrease in these properties. A stable nickel-based cluster solution is shown to form when the density and the surface tension increase at 0.02 wt % tin. When the temperature increases to 1650°C, the properties of the melts are characterized by a slight decrease in the surface tension and the density at a retained type of dependences.
期刊介绍：
Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
