Description
| - The gas reactor turbine blades produced from the Inconel 738 nickel-base superalloy were studied with the aim to assess the influence of high-temperature operation fatigue on the microstructure. High-resolution small-angle neutron scattering (SANS) provides an unique possibility of non-destructive characterization of precipitates in the blades. Two turbine blades in as-cast state and after operation were compared at different positions along their edge, where different thermal and stress loads are expected. Size distributions and relative volume fractions of gamma´-precipitates were evaluated from measured SANS spectra for each blade and individual position. It was found that the precipitate volume fraction increases towards the tip of both blades. The blade after operation exhibits a significant increase of the average size and volume of precipitates with respect to the as-cast blade, which can be explained by expected stronger precipitate coarsening under higher stresses. The prec...
