Paper Abstract

The size distribution of microstructural inhomogeneities in a turbine blade sample, not operated and built of IN738 Ni- based superalloy, has been investigated by Small-Angle Neutron Scattering. Data analysis has ben performed taking into account multiple scattering, that is not negligible due to the large thickness of the sample. Results show the presence of inhomogeneities with dimensions compatible with (gamma) phase particles, already observed by scanning and transmission electron microscopy.
