Abstract	A key premise in this case is the thesis that the kinetic process in 5-6 component HEAs can be considered as the self-diffusion of individual atoms with a diffusion coefficient D close to the corresponding value in single-component metals. This approach is justified by the fact that in HEAs, the atomic sizes of the individual components are very similar (deviations rᵢ from the average atomic radius r̅ do not exceed 5%). It should be noted that, at first glance, this deviation appears small, but it is precisely what enables the formation of the HEA state and the development of high macrostress values
