The distribution of phosphorus and sulfur impurities in the γ- and γ1-phases of single crystals of alloy ZhS36-VI is studied by high-resolution methods of transmission electron microscopy and microscopic x-ray spectrum analysis. It is shown that these impurities are mostly concentrated in the γ-solid solution, which contains local regions of their high content. The kind of the distribution of the impurities is preserved after testing for long-term strength; the nonuniformity of the distribution of sulfur between the γ- and γ1-phases becomes more manifested, especially for the composition with a high sulfur content.
