Abstract Scope The lead-cooled fast reactor (LFR) is a fourth-generation reactor design characterized by high temperatures and neutron dosage. Lead is also highly corrosive to structural alloys and can cause erosion at high flow velocities. Therefore, materials that can withstand this harsh environment must be studied for structural and system components. Ferritic alloys are promising candidates due to the high-temperature creep strength, resistance to damage from fast-spectrum neutrons, and the growth of protective oxide layers. However, there are limitations due to erosion and the joining of these materials into the complex geometries of system components. In this talk, mechanical property, and microstructural evolution of additively manufactured and conventionally joined FeCrAl based ferritic alloys before and after molten lead exposure at 500C will be presented. Corrosion testing was performed at 500˚C in lead flowing up to 3 m/s in the Lobo Lead Loop at the University of New Mexico.
