The dislocation structure evolution in the superalloy was studied by in-situ neutron diffraction tensile tests and line profile analysis. The proportion of screw-type dislocations increased in both fine and coarse ' structures, and dislocations were rearranged towards high-energy structures with weak dipole character, especially in the fine structure, due to its enhanced slip planarity.
