Multi-head attention network for prediction of irradiation embrittlement in reactor pressure vessel steels

npj Materials Degradation
The accurate prediction of irradiation embrittlement in reactor pressure vessel (RPV) steel remains challenging. Here, we develop a multi-head attention network (MHANet) and target the service-relevant shift in ductile-brittle transition temperature ...

Screening of Ceramic Filler Materials for a Packed‐Bed Thermal Energy Storage System With Lead as Heat Transfer Fluid

Energy Storage, Volume 8, Issue 7, October 2026.
ABSTRACT Liquid lead (Pb) is an attractive heat transfer fluid (HTF) for packed‐bed thermal energy storage (TES) systems aimed for high temperatures. However, liquid Pb is corrosive and its corrosivity increases with rising temperature. Therefore, compatibility tests of possible filler materials with Pb are mandatory.

The investigation of the carbon on irradiation hardening and defect clustering in RPV model alloy using ion irradiation and OKMC simulation

Nuclear Engineering and Technology
The precipitation of solutes is a major cause of irradiation hardening and embrittlement limiting the service life of reactor pressure vessel (RPV) steels. Impurities play a significant role in the formation of precipitation in RPV materials.

TA10 Titanium Alloy in HCl Solution: W‐Influenced Corrosion and Passivation Film Evolution

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT This work investigated the evolution of passive films of Ti–0.3Mo–0.8Ni (TMN) in 5 mol L−1 HCl and studied the influence of W on the anti‐corrosion properties of TMN. The intermittent electrochemical impedance spectroscopy test results showed that when TMN entered 5 mol L−1 HCl solution, the stability of the passive film first became stronger ...

Additive Manufacturing of Alumina‐Reinforced Elastomers

Advanced Engineering Materials, Volume 28, Issue 18, 23 September 2026.
Vat‐photopolymerized elastomers reinforced with platelet‐shaped alumina exhibited preferential orientation, reduced porosity, and significantly enhanced mechanical performance. A 3 wt% platelet loading increased tensile strength from 12.4 to 45.7 MPa, highlighting the critical role of filler morphology in elastomeric VPP composites.

Elastic Properties and Thermal Expansion Behavior of a Polycrystalline VMnFeCoNi High‐Entropy Alloy

Advanced Engineering Materials, Volume 28, Issue 18, 23 September 2026.
The high‐entropy alloy (HEA) V20Mn20Fe20Co20Ni20 (composition in at.%) can be made single‐phase face‐centered cubic (FCC) when annealed above 1338 K followed by water quenching. In this state, the alloy exhibits the greatest strength‐ductility combination of any quinary single‐phase FCC HEA.
