abstract = {The measurement of the lattice constant of the γ-matrix and γ′-phase by X-ray diffraction before and after creep experiments allows to see the changes of internal stress and strain states during creep. In this work three experimental alloys with systematically varied amounts of lattice misfit were studied. It was found that the separation of X-ray peaks of γ and γ′ after creep is directly dependent on the amount of lattice misfit. Also the distortion of the lattice, visible in the broadening of the respective rocking curves, was measured and found to be dependent on the lattice misfit as long as the γ/γ′-interfaces stay coherent. The lattice misfit is directly influenced by the alloy composition. Rhenium and ruthenium decrease the lattice misfit and modify the coherency stresses between γ- and γ′-phase, accordingly.},
