摘要

具有高构形熵的合金与传统合金有着根本的区别，因为它们含有的不是一种，而是五种或更多的基本元素，浓度在5到35 at之间。%。由于独特的元素组成，高熵合金可以具有不同寻常的功能性能，如高强度和耐磨性，优异的耐热性，良好的结构稳定性和良好的抗腐蚀和抗氧化性。综述了高熵合金的合成方法、高熵合金结构的计算机模拟方法和结果，以及高熵合金在耐腐蚀、耐热、耐辐射材料和生物医用材料等方面的应用。特别注意了这类合金作为防护涂层的应用前景。参考书目包括352篇参考文献。

High-entropy alloys: properties and prospects of application as protective coatings

Alloys with high configurational entropy fundamentally differ from traditional alloys as they contain not one, but five or more basic elements with concentrations of 5 to 35 at.% each. Owing to the unique elemental composition, high-entropy alloys can have unusual functional properties such as high strength and wear resistance, exceptional heat resistance, good structural stability and good resistance to corrosion and oxidation. The review considers methods of synthesis of high-entropy alloys, methods and results of computer simulation of the high-entropy alloy structures and applications of such alloys as corrosion-, heat- and radiation-resistant materials and biomedical materials. Particular attention is paid to the prospects for the use of such alloys as protective coatings. The bibliography includes 352 references.
