Název v původním jazyce

Investigation of microstructural changes in INCONEL 706 at high temperatures by In-situ small-angle neutron scattering

Popis výsledku v původním jazyce

The Ni-Fe based superalloy INCONEL 706 (IN706) has a complex microstructure and many A(3)B type phases, e.g., Ni3Al gamma', Ni3Nb gamma', Ni3Nb delta, or Ni3Ti eta precipitates can form. The various precipitates can also have different morphologies, i.e., plate, needle, cube, or disc shape, and some of them exist as co-precipitates-gamma'/gamma''. In the present study, in-situ measurements by small-angle neutron scattering (SANS) were performed to monitor the microstructural evolution at elevated temperatures. The SANS measurements were complemented by microstructural observations at room temperature by scanning electron microscopy and transmission electron microscopy (SEM and TEM). It is demonstrated that eta plates and gamma'' needles form directly at high temperatures. Cooling from high temperature produces fine dispersions of gamma'/gamma'' precipitates, which coarsen on reheating to lower stabilization temperatures (893 and 993 K). The final morphology of the gamma'/gamma'' co-...
