The temperature dependences of magnetic susceptibility and electrical resistance of a high entropy FeCoNiCrMn alloy. was studied. It was presented the results of researches by low-x-ray scattering of X-rays and Fourier analyzes of the profile of the diffraction peak. It was shown that the structure of alloy characterized by heterogeneities of nanometer size of different nature. Such heterogeneity should be considered as a consequence of the metastable state of the FeCoNiCrMn alloy. A thermodynamic analysis of the possible causes of the formation of such heterogeneities was carried out, which confirms the metastable state of investigated alloy.
