摘要

摘要研究了热处理（扩散退火、淬火、低温回火和高温回火）对高熵 35Fe-30Cr-20Ni-10Mo-5W 和 30Fe-30Cr-20Ni-10Mo-10W 合金的结构、相组成和耐腐蚀性的影响。通过在真空炉中烧结机械合金粉末，获得了含有不同浓度钨的 Fe-Cr-Ni-Mo-W 系高熵合金。结果表明，所获得的高熵合金对氯化钠水溶液的总抗蚀性和抗点蚀性高于石油和天然气工业中使用的工业生产的奥氏体抗腐蚀钢 316L。

The Effect of Heat Treatment and Tungsten Content on the Structure, Phase Composition, and Corrosion Resistance of High-Entropy Alloys of the Fe–Cr–Ni–Mo–W System

Abstract—The effect of heat treatment (diffusion annealing, quenching, low-temperature and high-temperature tempering) on the structure, phase composition, and corrosion resistance of high-entropy 35Fe–30Cr–20Ni–10Mo–5W and 30Fe–30Cr–20Ni–10Mo–10W alloys has been studied. High-entropy alloys of the Fe–Cr–Ni–Mo–W system with different concentrations of tungsten are obtained by sintering mechanically alloyed powders in a vacuum furnace. It is revealed that the total and pitting resistance of the obtained high-entropy alloys to aqueous solutions of NaCl is higher than that of industrially produced austenitic corrosion-resistant steel 316L used in the oil and gas industry.

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.
