The contribution deals with the chemical and structural heterogeneity of a creep resistant Ni-based alloy Inconel 713 LC. This material belongs to the cast poly-crystalline nickel super-alloys which are used for the production of circulating wheels of small combustion turbines for supplementary energetic units in aviation industry. In operational conditions of combustion turbines as part of turbo engines, blades of the circulating wheels are stressed in time, temperature and stress variable cycles during the loading procedure. The blades are exposed to a series of degradation factors such as high-temperature corrosion, fatigue processes and creep during the operation. Measurement of the chemical microheterogeneity of elements was realized in as-cast state before and after exploitation. As microanalytical complex was applied JEOL JXA 8600/KEVEX Delta V Sesame and EDS. In the analysis of chemical microheterogeneity, the concentrations of Al, Ti, Cr, Ni, Zr, Nb, Mo were measured in 101 points of the structure. Then the indices of dentritic microheterogeneity IH were estimated. The redistribution of elements is discussed.
