Opis:: The structure of a family of high entropy alloys based on the composition CoCrFeNi, to which Pd and Sn have been added, is presented. The results stem from combined investigations by atom probe tomography as well as by scanning and transmission electron microscopy on samples produced by arc melting. Although CoCrFeNi is of fcc structure, the sample is not homogeneous on atomic scale. The addition of Pd as a fifth element retains the fcc lattice with the indication of the coexistence of at least two additional phases. The addition of Sn changes the general structure considerably.

Opis:: The understanding of the structure and the stability of high entropy alloys is still incomplete and the mechanisms behind the composition-property relationships are unclear. One reason is that few systematic and accurate determinations of their composition-dependent structure on atomic level have been made. In this paper some results on the structure obtained by X-ray and neutron diffraction of the CoCrFeNi alloy, to which Pd, Sn and Cu have been added in different amounts, are reported. The investigations make it obvious that none of the alloys is completely homogeneous, as has earlier been suggested, and that they do not form a perfect solid solution.
