Investigation on the high-temperature creep and irradiated damage behaviours of plasma-facing components material fabricated by selective laser melting

Nuclear Fusion
Oxide dispersion-strengthened (ODS) steel is a promising structural material in fusion reactors, nanoparticles in matrix pin grain boundaries, and capture point defects and they delay the performance degradation caused by creep and irradiation.

Preliminary study on Hot Isostatic Pressing diffusion bonding of Fe–Cr–Al and CLF–1 steel for preparation of tritium permeation barrier

Nuclear Materials and Energy, 2023
In the internal cooling channel forming of the blanket component for fusion reactor, the combination of Fe-Cr-Al ferritic steel with RAFM steel (reduced activation ferritic/martensitic steel) can form alumina film and then be served as tritium permeation

A Systematic Framework for Risk Assessment of Fusion Blanket: Addressing Manufacturing Defects, Accident Scenarios, and Radioactive Release

Science and Technology of Nuclear Installations, Volume 2026, Issue 1, 2026.
The breeder blanket, as a critical component in fusion reactors, undertakes three essential functions: tritium breeding, neutron shielding, and thermal energy conversion. Serving as the primary plasma‐facing component, it operates under extreme conditions—including sustained high temperatures, intense neutron irradiation fluxes, significant ...

Machine Learning Applied to High Entropy Alloys under Irradiation

Advanced Engineering Materials, Volume 27, Issue 23, December 2025.
Designing alloys for extreme environments demands fast, trustworthy prediction. This review charts how machine learning—especially machine‐learned interatomic potentials and predictive models based on experiment‐informed datasets—captures the complexity of high‐entropy alloys in extreme environments, predicts phase formation, mechanical properties, and

Near Steady Late Pleistocene Tropical Denudation Rates in SW Madagascar

Journal of Geophysical Research: Earth Surface, Volume 130, Issue 7, July 2025.
Abstract Denudation is a key parameter controlling the evolution of the Earth's surface, the production of soils, the stability of relief, or the long‐term evolution of climate. Climate fluctuations conversely have a strong impact on denudation, but these complex feedback mechanisms are still under‐constrained.

Robust Assessment of Post‐Localisation Hardening Behaviour in Eurofer97 Using Inverse Finite Element Methods

Strain, Volume 61, Issue 1, February 2025.
ABSTRACT Constitutive behaviour of fusion‐relevant steels in the post‐necking regime is necessary for detailed design of future fusion device components. A finite element model updating (FEMU) procedure using digital image correlation (DIC), particle swarm optimisation (PSO) and a novel post‐necking constitutive law was developed.

Impact of Kr and Ar seeding on D retention in ferritic-martensitic steels after high-fluence plasma exposure

Nuclear Materials and Energy, 2018
Total deuterium (D) retention from the bulk material of reduced-activation ferritic-martensitic (RAFM) steel Eurofer’97 (EU’97) and commercial ferritic-martensitic grade P92 was traced experimentally by means of thermal desorption spectroscopy (TDS) and ...

From Fundamental Interfacial Reaction Kinetics to Macroscopic Current–Voltage Characteristics: Case Study of Solid Acid Fuel Cell Limitations and Possibilities

Advanced Materials Interfaces, Volume 11, Issue 20, July 16, 2024.
The electrolyte CsH2PO4, with high proton conductivity at 250 °C, is attractive for fuel cell applications. Using a model geometry to obtain the fundamental electrochemical parameters describing the oxygen reduction reaction at the CsH2PO4‐Pt‐gas interface and a 1D model of coupled mass and charge transport in porous cathodes, the measured polarization
