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

DBTT Reduction Enabled by SiO2-Bearing Flux in Submerged Arc Welds
The ductile-brittle transition temperature (DBTT) plays a critical role in determining the integrity of welded structures under common low-temperature service conditions. Fluxes are proven effective agents that significantly alter weld compositions and resulting microstructures.

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

The exposure of structural materials to the environment in nuclear power plants leads to aging through thermal and/or irradiation effects. One of the consequences of this aging is the shift of the ductile to brittle transition temperature (DBTT) towards ...

Influence of preheating on tungsten damage under pulsed hydrogen plasma exposure
Preheated tungsten plate behavior under multiple pulsed hydrogen plasma irradiations in the PW-7 plasma accelerator was investigated. The preheating temperature was 973 K, which is above the ductile to brittle transition temperature (DBTT ≈ 673 K).
