Moiré fringes for misfit measurements at incoherent y/y'-interfaces of nickel-base superalloys

Electron microscopy investigation of the structure of a compact extruded from nanopowder of nickel
(2007)
Changes in the structure of single-crystal (SC) superalloy SRR99 during creep at 980 °C and 200 MPa were investigated. Geometrical parameters of the y/y'-microstructure, y/y'-misfit, stresses in the phases and local misorientation of the structure were determined at defined points of the dendritic structure by use of X-ray diffraction (XRD), wavelength dispersive X-ray spectroscopy (WDXS), scanning (SEM) and transmission (TEM) electron microscopy. Correlation of the microstructural period and local misorientation of the structure with creep strain were found.
