Plasma–materials interaction issues for the International Thermonuclear Experimental Reactor (ITER) [PDF]

Journal of Vacuum Science and Technology A: Vacuum, Surfaces and Films, 1992
At the extreme conditions expected for some operating scenarios of the International Thermonuclear Experimental Reactor, commonly used heat-removal structures are unable to withstand either the high sputter erosion rates or power loads. Solutions to these lifetime and reliability problems by (1) changes in machine design and operation, (2) redeposition

High Radiation Resistance in the Binary W-Ta System Through Small V Additions: A New Paradigm for Nuclear Fusion Materials. [PDF]

Adv Sci (Weinh)
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.

Achieving Anti-Disproportionation Performance Enhancement and Distorted Inverse-Disproportionation Reaction Correction of Zr₂Fe-Based Hydrogen Isotope Storage Alloys via Element Substitution. [PDF]

Adv Sci (Weinh)
Undesirable phase transition behavior and anti‐disproportionation performance limit the hydrogen isotope storage of Zr2Fe alloy. With theoretical screening and experiments, partial Cu/Ni substitutions achieve full reversibility and significantly improve anti‐disproportionation properties.

Ga Doping Enables Precision Alloy-to-Wire Regulation: Synergistic Enhancement of the Mechanical Properties of CuSn Alloy and the Superconducting Properties of Nb₃Sn. [PDF]

Adv Sci (Weinh)
By adjusting Ga's doping in Cu–Sn alloy, an ultra‐high elongation of 100.8% is achieved in first time. Ga forms a stable solid solution structure and a stronger electron exchange with Cu. This enhances strength‐ductility synergistically by tuning SFE to balance twinning and slip.
