Research progress in weldability of austenitic stainless steel after neutron irradiation

open access: yesCailiao gongcheng
With the increasing service time of pressurized water reactor nuclear power plants, the weldability of austenitic stainless steel, used as a core structural material in reactors, gradually deteriorates due to neutron irradiation damage.

Investigation of microstructure defects in EUROFER97 under He+/Fe3+ dual ion beam irradiation

open access: yesNuclear Materials and Energy, 2018
Fusion like conditions for reduced activation ferritic/martensitic steels in the first wall are simulated with single Fe3+ and He+/Fe3+ dual ion beam irradiation of EUROFER97 at the Jannus laboratory, CEA Saclay, introducing a damage of 16 dpa and a ...

Mechanoluminescence of a Ba4Si6O16:Eu2+, Ho3+‐Containing Glass‐Ceramic: Experiments Under Different Loading Modes and Modeling

open access: yesphysica status solidi (a), Volume 223, Issue 10, 22 May 2026.
A glass‐ceramic from the BaO‐SiO2 chemical system emits light under mechanical loading provided it was submitted to UV irradiation prior to mechanical loading. This phenomenon is known as elasto‐mechanoluminescnence and, in the present case, it occurs thanks to the incorporation of a few percents of europium and holmium and an original synthesis route ...

Helium bubbles evolution mechanism of SA508-3/52 joint and its effect on nanoindentation hardness and swelling

open access: yesHeat Treatment and Surface Engineering
After metallographic corrosion of dissimilar metal welded joints, a distinct uncorroded bright band, referred to as the ‘white bright band’ (WBB), is often observed on the austenite side immediately adjacent to the fusion line.

Comparison of blistering of W bulk and film deposited by magnetron sputtering under helium irradiation

open access: yesNuclear Materials and Energy, 2017
In this work, the W bulk prepared by powder sintering and W film deposited by magnetron sputtering were simultaneously exposed to the helium ions with the energy of 60keV and fluence of 1.0 × 1022 m−2 at room temperature.

Streakline flow visualization of discrete hole film cooling with holes inclined 30 deg to surface [PDF]

open access: yes
Film injection from three rows of discrete holes angled 30 deg to the surface in line with mainstream flow and spaced 5 diameters apart in a staggered array was visualized by using helium bubbles as tracer particles.

Vortex Splitting in Subcritical Nonlinear Schrodinger Equation

open access: yes, 2008
Vortices and axisymmetric vortex rings are considered in the framework of the subcritical nonlinear Schrodinger equations. The higher order nonlinearity present in such systems models many-body interactions in superfluid systems and allows one to study ...

Characterization of a Recyclate‐Based MgO‐Steel Composite As‐Sintered Inert Anode Candidate After Exposure to Cryolite Electrolysis

open access: yesAdvanced Engineering Materials, Volume 28, Issue 10, 20 May 2026.
Carbon‐free inert anodes are essential for decarbonizing aluminum electrolysis. This study investigates a recyclate‐based MgO‐316L steel composite anode tested under galvanostatic Hall–Héroult conditions in cryolite at 1000°C. Microstructural analysis reveals selective MgO fluorination, spinel and oxide layer formation, electrolyte infiltration, and ...

Growth of multifractal tungsten nanostructure by He bubble induced directional swelling

open access: yesNew Journal of Physics, 2015
Helium (He) plasma irradiation to tungsten (W) leads to morphology changes in nanometer scale by the formation and growth of He bubbles. Initially pinholes and protrusions are formed on the surface followed by the formation of nanostructures.

Molecular–Polymeric Hybrid Photocathodes for CO2 Reduction: A Modular Approach to Sustainable Photoelectrocatalysis

open access: yesChemElectroChem, Volume 13, Issue 10, 19 May 2026.
CP/PPy/Re–Ru is a hybrid molecular–polymeric photocathode prepared in a simple two‐step process by depositing catalytically active complexes onto a polypyrrole backbone on carbon paper. Under photoelectrocatalytic conditions, it achieves 60%–70% Faradaic efficiency for CO. Even in membrane‐free operation, continuous CO evolution is maintained for up to
