Созданный одним из первых более 20 лет назад высокоэнтропийный пятикомпонентный сплав CoCrFeNiMn (сплав Кантора) по-прежнему привлекает внимание исследователей в области физического материаловедения по причине возможного его применения в различных отраслях промышленности благодаря удачному сочетанию прочностных и пластических свойств. К настоящему времени накоплен большой экспериментальный материал по управлению свойствами этого сплава. В настоящей работе выполнен обзор публикаций отечественных и зарубежных авторов по различным направлениям улучшения свойств этого сплава: легированием, выделениями, термической обработкой, использованием фазовых диаграмм Calphad. Проанализирована роль легирования бором, ванадием, алюминием, кремнием, ниобием; роль нановыделений, влияние различных режимов термической и деформационной обработок. Сделан вывод о необходимости проведения экспериментов по легированию ВЭС цирконием и ниобием, хорошо зарекомендовавшими себя в упрочнении сталей. Показано, что создание и модифицирование свойств пятикомпонентных ВЭС возможно при использовании компьютерных программ Calphad, разработанных для расчета диаграмм состояния. Проанализированные результаты публикаций по термодинамическому описанию пятикомпонентных сплавов подтверждены сравнением фазовых диаграмм с имеющимися экспериментальными данными. Показано, что на основе расчета фазовых диаграмм Calphad возможен дизайн нового поколения ВЭС.

First created over 20 years, high-entropy five-component alloy CoCrFeNiMn (Cantor alloy) still attracts the attention of researchers in the field of physical materials science because its possible application in various industries due to a successful combination of strength and plastic properties. To date, a large amount of experimental material has been accumulated on how to control the properties of this alloy. This article reviews the publications of Russian and foreign authors in two areas of improving the properties of this alloy: alloying, precipitation and heat treatment and the use of Calphad phase diagrams. In the first direction, the role of alloying with B, Vi, Al, V, Si, Nb is analyzed; nanoprecipitations, various modes of thermal and deformation processing. It is concluded that it is necessary to conduct experiments alloying HEA with Zr and Nb, which have proven themselves well in steels hardening. The creation and modification of the properties of five-component HEA is possible using the Calphad computer software developed for calculating state diagrams. The results of publications on the thermodynamic description of five-component alloys analyzed in the article are confirmed by comparing the phase diagrams with the available experimental data. It is shown that the development of a new generation of HEAs is possible based on the calculation of the Calphad phase diagrams.
