Effect of irradiation on nanoprecipitation in EM10 alloy - Comparison with Eurofer97

Abstract Atom Probe Tomography investigations of EM10 and EUROFER alloys after both 1 MeV electrons and 2 MeV Fe2+ ions irradiations at 300 °C and up to doses of 0.6 dpa were performed. SiNiPMn(-Cu) enriched clusters were observed only in EM10 alloy. Phosphorus was found to be necessary for cluster formation. Segregation of Si, Ni, P, Mn elements were measured at a Grain Boundary and a dislocation. Cr clusters near a dislocation were noticed.
