Abstract—The effect of exposures in the range of 500–10 000 h at heating temperatures of 450–750°C on changes in the structure and properties of steel 08Kh18N10T has been studied. It has been found that, in the early stages of thermal aging at 450–550°C, the precipitates of finely dispersed carbides are formed, coherent with the austenitic matrix. With an increase in the holding time and aging temperature to 650°C, the sizes of Me23C6 carbide particles sharply increase, which, under a certain combination of temperature–time parameters, evolve into the σ phase with low coherence with the γ-solid solution. However, this phenomenon has little effect on the mechanical properties at room temperature.
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.
