Abstract—The microstructure, phase composition, and oxidation resistance of as-cast high-entropy alloys (HEAs) Al_0.25CoCrFeNi and Al_0.25CoCrFeNiCuAg_x (x = 0, 0.1, 0.2) have been studied. Oxidation was carried out at 700°C for 50 h in air. During the experiment, curves for the dependence of the specific weight gain on the exposure time were plotted. It has been shown that the introduction of copper has a slight effect on the resistance of the base Al_0.25CoCrFeNi HEA to oxidation, while additional (to copper) alloying with silver worsens the resistance of the samples to high-temperature gas corrosion.

高熵合金 Al0.25CoCrFeNi 和 Al0.25CoCrFeNiCuAgx (x = 0, 0.1, 0.2) 的显微结构、相组成和抗氧化性研究

摘要研究了铸态高熵合金（HEAs）Al0.25CoCrFeNi 和 Al0.25CoCrFeNiCuAgx（x = 0、0.1、0.2）的微观结构、相组成和抗氧化性。在 700°C 的空气中氧化 50 小时。在实验过程中，绘制了比重增加与暴露时间的关系曲线。实验结果表明，铜的加入对基体 Al0.25CoCrFeNi HEA 的抗氧化性有轻微影响，而额外加入（除铜以外的）银合金则会降低样品的抗高温气体腐蚀性能。

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.
