    In situ observation of morphological changes of gamma ' precipitates in a pre-deformed single-crystal Ni-base superalloy

  • Original language description

    Exposure of a superalloy to an external load results in anisotropic coarsening of the gamma' precipitates, so-called rafting. It was reported in the past that gamma' rafting can also occur as a result of purely thermal treatment, without the simultaneouspresence of an external load, if the specimen has been pre-deformed at relatively low temperature. The evolution of gamma' morphology in pre-deformed specimens of SCA425 Ni-base superalloy was examined in the present study. Unlike in the previous experiments, the compressive stress was used for pre-straining. In situ small-angle neutron scattering (SANS) was employed, which enabled the determination of the morphology directly at high temperature.
