High Radiation Resistance in the Binary W‐Ta System Through Small V Additions: A New Paradigm for Nuclear Fusion Materials

Advanced Science, Volume 12, Issue 20, May 29, 2025.
Refractory high‐entropy alloys exhibit superior radiation tolerance, but face fabrication challenges due to complex compositions. It is demonstrated that reducing the number of alloying elements does not compromise radiation resistance in a novel W‐Ta‐V highly‐concentrated refractory alloy.

Orientation‐dependent mechanical responses in molybdenum‐rhenium alloys evaluated via micro‐pillars

Engineering Reports, Volume 6, Issue 10, October 2024.
Orientation‐dependent compressive properties are found in Mo‐14Re and Mo‐42Re, but are not found in Mo and Mo‐5Re, which may be attributed to activated multi‐slip planes as increased Re. Solid solution effect of Re not only rely on orientations, but also on Re content. Softening effect occurs in both [100] and [110] Mo‐5Re.

The Influence of Mo Content and Annealing on the Oxidation Behavior of Arc‐Melted Cr–xMo–8Si Alloys

Advanced Engineering Materials, Volume 26, Issue 17, September 2024.
Cr–xMo–8Si alloys (x = 10, 20, and 25 at%) show high potential for a new class of lightweight refractory alloys for high‐temperature applications. Especially worthwhile of further development is the Cr–25Mo–8Si alloy with extremely low mass gain and continuous SiO2 subscale formation, preventing internal oxidation.

Crack‐Free Tungsten Fabricated via Laser Powder Bed Fusion Additive Manufacturing

Advanced Functional Materials, Volume 34, Issue 12, March 18, 2024.
Additive manufacturing of tungsten (W) is challenging due to its high melting point, and brittleness from GB oxides. In this study, the processing of W through laser powder bed fusion is investigated. Parts are fabricated under argon (Ar) and nitrogen (N2).
