The robust electrochemical sustainability of additively manufactured high‐performance nanocomposites is substantially dependent on overcoming material selection, process optimization, operational scalability, and design flexibility challenges. Integrating transition metal dichalcogenides into metal‐matrix composites, laser powder bed fusion directly ...

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.

Heat Treatment Effects on Microstructures and DBTT of F82H Steel Doped with Boron and Nitrogen
Effects of doping with 60 ppm B and/or 200 ppm N and heat treatments on the microstructures and the ductile-brittle transition temperature (DBTT) have been studied for ferritic/martensitic steel F82H. Prior austenitic grain size of standard F82H decreased from about 120 to 30 μm and also the DBTT decreased by about 50°C when the normalizing ...

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.

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).

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).
