Abstract
The present work provides new insight into how the dislocation density and coherent scattering domain size change during high-temperature creep deformation in G91, G92 and 14YWT ODS steels at 650°C and 750°C via synchrotron X-ray experiments. The results presented here will contribute to the understanding of high-temperature creep deformation effects in these three advanced candidate reactor structural materials, and provide experimental data for future modeling endeavors of dislocation behavior during creep in advanced steels.
