The development of the theory and technology of high-entropy alloys (HEA), consisting of several basic elements, poses a number of urgent tasks for researchers to comprehensively study the properties of new materials that determine the areas of their practical application. This report presents an overview of scientific publications devoted to the study of the mechanical properties of the most studied HEAs based on the CoCrFeNiMn transition metal system, as well as to the study of the influence of certain types of welding on the quality indicators of welded joints. As a result of the work performed, it was found that the strength and plastic properties of the considered HEAs correspond to the best samples of high-alloy austenitic steels used for cryogenic technology, and have the prospect of further improvement.
