Abstract—Using high-temperature X-ray diffraction, the thermal expansion coefficient was determined in VNS9Sh steel, Mg-8Li-1Al alloy, and Si+SiC multilayer coating layer. The TCLE value of the γ phase significantly exceeds the TCLE of the α phase, which corresponds to the data for austenitic and martensitic steels, while the TCLE values of each phase depend on the composition of phases. The TCLE value in the β phase of a magnesium alloy exceeds the TCLE value for the α phase, and this difference increases with an increase in temperature. The TCLE value of the α phase in the direction of the “c” axis (αc) is higher than in the basal plane (αa). It is shown that the advantage of the high-temperature X-ray diffraction method for assessing the TCLE is the ability to measure them in thin surface layers, as well as the ability to evaluate the TCLE of individual phases and their anisotropy in multiphase, textured objects.
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.
