Mechanical and microstructural characterization of electron beam welded reduced activation oxide dispersion strengthened - Eurofer steel

The microstructure of the weld and heat-affected zone as well as the fracture surface of the samples were examined using optical and scanning electron microscopy, dual-beam SEM/FIB, low magnification and analytical transmission electron microscopy. The changes of the mechanical properties can be well correlated with the detected changes of micro- and nano-structure.
