Impact of friction stir welding on the microstructure of ODS steel [PDF]

Journal of Nuclear Materials, 2017
We have assessed the impact of the welding parameters on the nano-sized oxide dispersion and the grain size in the matrix of an ODS steel after friction stir welding. Our results, based on combined small angle neutron scattering and electron microscopy, reveal a decrease in the volume fraction of the particles smaller than 80 nm in the welds, mainly ...
