Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT The heterostructured 1T‐MoS2‐based bimetallic sulfides are promising bifunctional electrocatalysts for alkaline overall water splitting. However, the controllable synthesis of these catalysts is hindered by the ready conversion of Mo species to 2H‐MoS2 and the tedious heterostructure engineering during sulfidation.

Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT A thermomechanical strategy based on rolling‐annealing cyclic (RAC) was developed to regulate defect architecture and precipitation behavior in a (FeCoCrNi)94Al3Ti3 high‐entropy alloy. Intermediate annealing during rolling enables progressive grain refinement and introduces a high density of twins, stacking faults, and dislocations, forming a ...

Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT The exceptional ductility of face‐centered cubic high/medium‐entropy alloys (H/MEAs) is counterbalanced by intrinsically restrained yield strength, fundamentally compromising their application in structural and functional materials. Here, a novel carbon (C)‐driven precipitation strategy is introduced to promote discontinuous precipitation (DP)
