Abstract—In recent years, the unique physical and mechanical properties of high-entropy alloys (HEAs) have been the subject of increased attention of researchers. The study of the thermodynamic characteristics of such materials may be of interest for formulating the principles of the formation of structures with the required functional characteristics. Since the processes of structure and phase formation, as well as the diffusion mobility of atoms, the mechanism for the formation of mechanical properties, and thermal stability, differ significantly from similar processes in traditional alloys, HEAs are singled out into a special group of materials. The article presents a brief overview of the results of obtaining a high-entropy alloy by the combined method. At the first stage, a precursor layer was deposited by cold gas dynamic spraying (CGDS), and at the second stage, it was subjected to high-energy action using a laser. An alloy of the Al–Cr–Ni–Co–Fe type has been studied. By varying the ratio of the components, it was possible to obtain an almost equimolar composition for this system. A prediction of properties and structure is made on the basis of the phase composition of the system.

激光在钢基体上制备Al-Cr-Ni-Co-Fe多组分体系

摘要近年来，高熵合金(HEAs)独特的物理力学性能越来越受到研究人员的关注。研究这类材料的热力学特性可能有助于阐明具有所需功能特性的结构的形成原理。由于HEAs的结构和相形成过程，以及原子的扩散迁移率，机械性能和热稳定性的形成机制与传统合金的类似过程有很大不同，因此HEAs被单独列为一类特殊的材料。本文简要介绍了用复合方法获得高熵合金的结果。第一阶段采用冷气体动态喷涂(CGDS)沉积前驱体层，第二阶段采用高能激光作用前驱体层。研究了一种Al-Cr-Ni-Co-Fe型合金。通过改变组分的比例，可以得到该体系的几乎等摩尔的组成。根据体系的相组成对其性能和结构进行了预测。

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.
