The Effect of Precipitate Evolution on Austenite Grain Growth in RAFM Steel [PDF]

Materials, 2017
To study the effects of various types of precipitates and precipitate evolution behavior on austenite (size and phase fraction) in reduced activation ferritic/martensitic (RAFM) steel, RAFM steel was heated to various austenitizing temperatures. The microstructures of specimens were observed using optical microscopy (OM) and transmission electron ...

Impact of seeded plasma impurities on D retention in RAFM steels

Nuclear Materials and Energy, 2020
The effect of He seeding (He+ ion fraction, cHe+, of ~5 and ~10%) to D plasma (ion flux ~ 1.5–2 × 1021 m−2s−1, sample temperature ~ 373 K, and incident ion energy ~ 100 eV) on D retention in various reduced-activation ferritic/martensitic (RAFM) steels ...

Microstructural Evolution of the TLP Joints of RAFM Steel during Aging and Creep

Metals, 2022
In this study, transient liquid-phase (TLP) bonding was adopted to obtain a reliable reduced-activation ferritic/martensitic (RAFM) steel joint with Fe-Si-B amorphous foil. The aging tests and creep tests of the TLP joints were carried out at 550 °C to study the microstructural evolution in the service process.

Microstructure characterization of ODS-RAFM steels [PDF]

MRS Proceedings, 2008
ABSTRACTResults of the microstructural characterization of four different RAFM ODS Eurofer 97 batches are presented and discussed. Analyses and observations were performed by nuclear microprobe and scanning and transmission electron microscopy. X-ray elemental distribution maps obtained with proton beam scans showed homogeneous composition within the ...

An improved dislocation density reliant model to address the creep deformation of reduced activation ferritic martensitic steel

Forces in Mechanics, 2022
The blanket module of nuclear fusion reactor is proposed to be made of reduced activation ferritic martensitic (RAFM) steel. Thus, in order to prevent the unprecedented failure, the creep response of RAFM steel must be studied meticulously.
