Microstructure Refinement and mechanical properties improvement of EUROFER97 steel

, 2022
EUROFER97 steel for nuclear fusion applications are usually manufactured by hot rolling and subsequent heat treatments: austenitization at 980 °C for 30 minutes, rapid cooling and tempering at 760 °C for 90 minutes. The aim of this work is to refine the microstructure of traditional EUROFER97 steel by means of a thermo-mechanical treatment, in order to

Nanoindentation and TEM to Study the Cavity Fate after Post-Irradiation Annealing of He Implanted EUROFER97 and EU-ODS EUROFER. [PDF]

Micromachines (Basel), 2018
The effect of post-helium irradiation annealing on bubbles and nanoindentation hardness of two reduced activation ferritic martensitic steels for nuclear fusion applications (EUROFER97 and EU-ODS EUROFER) has been studied. Helium-irradiated EUROFER97 and

Technological aspects in blanket design: Effects of micro-alloying and thermo-mechanical treatments of EUROFER97 type steels after neutron irradiation [PDF]

, 2021
Presently available data on neutron irradiation damage raise doubts on the feasibility of using EUROFER97 steel for a water-cooled starter blanket in a DEMO reactor, since the ductile-to-brittle transition temperature (DBTT) increases significantly for ...

Microstructural insights into EUROFER97 batch 3 steels

Nuclear Materials and Energy, 2023
Extensive analytical electron microscopical analyses were carried out from the micrometer scale down to the nanometer scale to characterize three variants of the 9% reduced activation ferritic martensitic (RAFM) steel EUROFER97/3. No huge microstructural differences were observed between the three grades.

Microstructural features in additively manufactured EUROFER97 components

Fusion Engineering and Design, 2021
Abstract By uncoupling the manufacturability from the design process, additive manufacturing of RAFM steels like EUROFER97 can open significant design freedom for components in fusion reactors, e.g., breeding blankets and divertor applications. As mechanical properties of RAFM steels are based on their specific microstructure and high number density

Dose Dependence of Micro-Voids Distributions in Low-Temperature Neutron Irradiated Eurofer97 Steel [PDF]

, 2019
The microstructural effects of mixed spectrum neutron irradiation at 250 °C and 300 °C, for 2.7 dpa, 8.4 dpa, and 16.3 dpa doses, have been investigated in standard Eurofer97 (0.12 C, 9 Cr, 0.48 Mn, 0.2 V, 1.08 W, 0.14 Ta wt%) by means of small-

Influence of traps reversibility on hydrogen permeation and retention in Eurofer97

Nuclear Fusion, 2022
Abstract The presence of three trapping sites in Eurofer97 and the diffusion and trapping parameters obtained in a previousarticle are confirmed using an additional thermal desorption spectrometry experiment. Using these parameters, permeation cycles are simulated using the diffusion–reaction code mhims in order to study the influence of

Effect of neutron irradiation to 0.7 and 1.4 dpa on the tensile mechanical properties and microstructure of EUROFER97 steel [PDF]

, 2023
Several grades of reduced-activation ferritic-martensitic (RAFM) steels have been proposed for fusion applications (e.g., blanket first wall) since the 1990s all over the world.

Thermal diffusivity, microstructure and nanohardness of laser-welded proton-irradiated Eurofer97

Journal of Nuclear Materials, 2023
Eurofer97 steel, a candidate structural material for future fusion reactors, was examined following 1.9 MeV proton-irradiation up to 0.91(5) dpa at 450 ◦C with and without a prior post-weld heat treatment at 760 ◦C for 4 hours in a laser-welded state. A nanoindentation study found a pile-up corrected nanohardness of 4.0(4) GPa in the as-welded fusion ...
