A cryogenic probe for in situ delivery of gaseous samples for neutron scattering

Journal of Applied Crystallography, Volume 59, Issue 2, Page 700-704, April 2026.
We describe an optimized gas‐delivery stick for use with top‐loading cryostats for neutron scattering measurements.This laboratory note describes an optimized solution for the delivery of gaseous samples for neutron scattering measurements. The original design to accomplish this, though effective, was not ideal from a use and maintenance perspective ...

Multifaceted Behavior and Functional Versatility of Ferritic Stainless Steels, Part I: Applications and Processing, a Review

steel research international, Volume 97, Issue 3, Page 1201-1225, March 2026.
This review investigates the processing‐microstructure‐property relationships in ferritic stainless steels (FSSs). It highlights advances in deformation behavior, heat treatments, surface modifications, and alloying effects. Theoretical models, including Johnson‐Mehl‐Avrami‐Kolmogorov, Arrhenius, nucleation theory, and diffusion theories, are discussed

Microstructural Evolution and Mechanical Performance of Plasma‐Assisted Hybrid Friction Stir Welded Dissimilar Aluminum–Copper Joints

Advanced Engineering Materials, Volume 28, Issue 3, 4 February 2026.
Plasma‐assisted hybrid friction stir welding of dissimilar AlCu joints employs localized plasma preheating to balance heat input and enhance plastic flow. The optimized process reduces axial force by up to 35%, refines the microstructure, and achieves ≈96% joint efficiency.

Joining of tungsten with low-activation ferritic–martensitic steel and vanadium alloys for demo reactor

Nuclear Materials and Energy, 2018
The conceptual designs of the blanket and the helium-cooled divertor of the DEMO reactor require joining of reduced activation steel (for example RUSFER EK-181, EUROFER, etc.) and tungsten. Significant differences in their physical properties can lead to
