Abstract
A two component Al–Ba system has been studied in which intermetallic compounds are formed that are stable at temperatures above the melting points of both barium and aluminum. This allows us to consider barium as a promising alloying element for aluminum alloys operating at high temperatures, which is also characterized by relatively high vapor pressure. Widespread use of aluminum–barium alloy in various fields of metallurgy for the preparation of alloys and complex modification of steels and cast irons, where aluminum improves the quality of steels, acting as a reducing agent for iron in its oxide compounds, and barium promotes the graphitization of cast irons, leads to improved structures of pearlitic and ferritic compounds. Taking into account the high vapor pressure of Ba in the aluminum–barium system is necessary when analyzing compositions in pressure–temperature–composition coordinates (p–T–x state diagrams), which can be used in the development of ternary or higher alloys containing aluminum and barium.
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.
