Effect of Oxygen and Bismuth Impurities on the Structural and Physicochemical Properties of Nickel Melts
There is a lack of publications devoted to the combined influence of oxygen and bismuth impurities on the structural and physicochemical properties of nickel melts or heat-resistant alloys based on it. This study examines the state of pure nickel melts and nickel containing (0.005–0.01) bismuth and oxygen during the refining process from oxygen and bismuth impurities. The influence of these impurities on the structural and physicochemical properties was studied, evaluated according to the parameters of density and surface tension of the melts. In nickel melts with bismuth and oxygen, a compression effect and negative deviation from Raoult’s law were observed. An effect of increased surface tension of a nickel melt containing oxygen with increasing bismuth concentration was found, which corresponds to the isotherm of desorption of excess substance from the surface into the bulk.
期刊介绍：
Inorganic Materials: Applied Research contains translations of research articles devoted to applied aspects of inorganic materials. Best articles are selected from four Russian periodicals: Materialovedenie, Perspektivnye Materialy, Fizika i Khimiya Obrabotki Materialov, and Voprosy Materialovedeniya and translated into English. The journal reports recent achievements in materials science: physical and chemical bases of materials science; effects of synergism in composite materials; computer simulations; creation of new materials (including carbon-based materials and ceramics, semiconductors, superconductors, composite materials, polymers, materials for nuclear engineering, materials for aircraft and space engineering, materials for quantum electronics, materials for electronics and optoelectronics, materials for nuclear and thermonuclear power engineering, radiation-hardened materials, materials for use in medicine, etc.); analytical techniques; structure–property relationships; nanostructures and nanotechnologies; advanced technologies; use of hydrogen in structural materials; and economic and environmental issues. The journal also considers engineering issues of materials processing with plasma, high-gradient crystallization, laser technology, and ultrasonic technology. Currently the journal does not accept direct submissions, but submissions to one of the source journals is possible.
