Additively manufactured AISI 316 L stainless steel samples were heat treated at temperatures from 400 °C to 1100 °C, and the corrosion behavior in chloride environments was electrochemically studied. Heat treatments 650 increased grain size treatment formed MnCr2O4 inclusions. Also, these postprocessing techniques reduce hardness porosity. polarization resistance maintained pitting mechanisms of additively samples. higher reduced but changed mechanisms.
For improved performance of the components in a fusion reactor, an increased application temperature for structural materials such as 9%Cr reduced activation steels is crucial. The improvement current generation (i.e. EUROFER) one aims EUROfusion programme advanced steels. goal this work to determine most effective thermo-mechanical treatment ferritic martensitic with respect high-temperature strength. Compatibility these treatments industrial production processes essential. In present...

An advanced breeding blanket based on Dual Coolant Lithium Lead concept with single module segment architecture, designed for European DEMO, certainly aligned such objective. This work describes some recent outcomes efforts carried out framework Prospective R&D Work Package EUROfusion develop this...
Copper nitride (Cu3N) has gained significant attention recently due to its potential in several scientific and technological applications. This study focuses on using Cu3N as a solar absorber photovoltaic technology. thin films were deposited glass substrates silicon wafers via radio-frequency magnetron sputtering at different nitrogen flow ratios with total pressures ranging from 1.0 5.0 Pa. The films’ structural, morphology, chemical properties determined XRD, Raman, AFM, SEM/EDS...
This work aims to fill a gap in the H transport database for niobium and vanadium, materials proposed fabrication of tritium extraction systems.
