Optimization on the microstructure and mechanical property of ODS-RAFM steel
Materials LettersA strategy for overcoming strength-ductility tradeoff of RAFM steel is realized through the introduction of numerous nanoparticles homogeneously dispersed in ultrafine-coarsen (bimodal grained) grained ODS steel matrix. Optimized the interface of Y2O3 oxide by in-suit grown carbide coatings, significantly improving the dispersion state to achieve dense

Modeling the constitutive behavior of RAFM steels under irradiation conditions
Journal of Nuclear Materials, 2011Abstract A coupled viscoplastic deformation damage model will be presented which is modified to take into account irradiation induced hardening and its recovery due to inelastic deformation and/or high temperature annealing. The model allows the prediction of the constitutive behavior of RAFM steels under arbitrary creep-fatigue and irradiation ...

Oxidation behavior of 9Cr-RAFM steel at high temperature
Ironmaking & Steelmaking: Processes, Products and ApplicationsThe effect of yttrium on the mechanism of oxidation film formation of the 9Cr reduced activation ferritic/martensitic (9Cr-RAFM) steel was investigated. Four alloys yttrium contents ranging from 0 to 0.065% were melted in a vacuum induction furnace and subjected to continuous isothermal oxidation experiments.

Determining irradiation damage and recovery by instrumented indentation in RAFM steel
Journal of Nuclear Materials, 2011Abstract The mechanical behavior of specific reduced-activation ferritic-martensitic steels (RAFM), designed for fusion applications, is investigated in the present study. Eurofer97 and F82H-mod specimens have been neutron-irradiated in the High Flux Reactor at Petten (HFR) up to a dose of 15 dpa at 250–450 °C. An indentation method [1] , making use

Effect of tungsten on tensile properties and flow behaviour of RAFM steel
Journal of Nuclear Materials, 2013Abstract Effect of tungsten in the range of 1–2 wt.% on tensile properties and flow behaviour of 9Cr–W–Ta–V Reduced Activation Ferritic–Martensitic (RAFM) steel has been investigated. The tungsten in the investigated range was found to have only minor effect on the tensile properties of the steel over the temperature range of 300–873 K and at a ...

Surface studies on the characterization of RAFM steel after deuterium plasma exposure
Surfaces and Interfaces, 2019Abstract Previous works have identified the potential for preferential sputtering of low/middle-Z elements in the reduced-activation ferritic-martensitic (RAFM) steels, leaving behind a W-enriched surface, which could then potentially reduce further sputtering of Fe and other elements in the steel.

Effect of Melting Processing on Tensile Properties and Microstructure of New RAFM Steel
18th International Conference on Nuclear Engineering: Volume 2, 2010All of the RAFM steels only safely used under 550°C, that is not enough for the next reactor. An new RAFM steel was melted by non-vacuum induction melting (VIM) and electro-slag remelting (ESR), followed by hot-forging and rolling into rods and plates.
