Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT The inherent brittleness of hardmetals stems from the rigid covalent bond in the ceramic matrix and the sharp ceramic/metal interface, which restricts the nucleation and motion of dislocations. In this study, a novel strategy is proposed to activate significant dislocation behaviors in the WC matrix by employing a non‐equiatomic CoNiFeCr ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Giga‐casting, a near‐net‐shape manufacturing process widely used in sectors such as new energy vehicles and aerospace, demands aluminum alloys with high integration, efficiency, and comprehensive performance. However, traditional die‐cast alloys still face two core bottlenecks: the strength–ductility trade‐off and high‐temperature ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Laser powder bed fusion (LPBF) can fabricate high‐entropy alloys (HEAs) with refined microstructure and enhanced mechanical properties. However, the deformation and fatigue mechanisms of Al‐containing HEAs produced by LPBF remain unclear. In this work, we systematically investigate the tensile properties, deformation mechanisms, and high‐cycle

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Refractory complex‐concentrated alloys (RCCAs) show exceptional promise for extreme‐environment applications, yet intermediate‐temperature instability (0.4–0.6 Tm) and plasticity degradation severely constrain their development. This work provides an effective strategy to transform the inherent intermediate‐temperature instability into a ...

Asian Politics &Policy, Volume 18, Issue 2, April 2026.ABSTRACT This study reframes Hong Kong's Legislative Council geographical constituency elections as a case of limited competition produced by institutional design. Using candidate‐level data, we examine how organizational resources and competition structure shape electoral outcomes under a mixed system that combines proportional representation in GCs ...
