In-situ neutron diffraction studies are performed to characterize the micromechanical deformation occurring during tensile creep of single-crystal nickel-based superalloys with negative lattice parameter misfits and cobalt-based superalloys with positive lattice parameter misfits. The loading responses of the matrix gamma phase and the precipitate gamma-prime phase are distinct, and the creep deformation of rafted microstructures is compared to non-rafted microstructures in both cobalt-based and nickel-based superalloys.
