Description	The chemical microheterogeneity of elements in two cast blades of the first stage of a gas turbine was measured. The first blade was measured in as-cast state, the second one after operation. By means of an original method, the microheterogeneity indíces IH and the effective partition coefficients kef were established. Using a metallographic method, the interdendritic distances, 2L = 32,8 mikro m, of the creep-resisting nickel-alloy blades were measured. By means of the Brody-Flemings (BF) heterogeneityy model and with the help of mathematical and statistical methods, a relation between the parameters IH and kef and parameter a = D /L2 of the BF model has been derived. Then the numerical values of parameter alfa from measured heterogeneity data (IH and kef) were calculated and a comparíson was made with literature data. By means of numerical values of parameter alfa it was possible: - to evaluate the relations among diffusion coefftcients D of element of nickel-based alloy (these elements can segregat The chemical microheterogeneity of elements in two cast blades of the first stage of a gas turbine was measured.
