Abstract: Microstructure of Waspaloy and DT750 Ni-base superalloys was investigated after the heat treatment as well as after long thermal exposure by Small-Angle Neutron Scattering (SANS). The SANS results clearly showed that there are large differences even between samples of the DT750 superalloy produced using different facilities. The modified heat treatment used for DT750 suppressed the formation of secondary precipitates. A strong influence of the thermal exposure on the superalloy microstructure was observed which can have an impact on the mechanical properties.
