MXene‐Based Materials Contribute Better Alkali Metal–Chalcogen Batteries: Progress, Challenges, and Perspectives

Rare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Alkali metal–chalcogen batteries (AMCBs) are one of the most promising next‐generation energy storage systems because of their high energy density and reasonably low cost. However, the practical application of AMCBs is severely hindered by the volume expansion of the chalcogen cathode, the shuttle effect of polychalcogenides, and unstable ...

A Review on Cracking in Laser Additive Manufacturing of Nickel‐Based Superalloys: Types, Formation Mechanisms, and Suppression Strategies

Rare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Nickel‐based superalloys (Ni‐based superalloys) have attracted extensive attention in laser additive manufacturing (LAM) due to their capability to directly fabricate complex and high‐performance structural components. However, the rapid melting and solidification inherent to LAM result in intense thermal cycling, which induces high residual ...

Velocity‐Iterative Directional Annealing Enables Ultra‐Elongated Columnar Grains and Exceptional Ductility in TiAl Alloys

Rare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT This study introduces a novel velocity‐iterative directional annealing (IDA) strategy to overcome stagnation challenges in columnar grain growth of Ti‐48Al‐2Cr‐2Nb alloys. By dynamically adjusting hot zone migration rates across iterative cycles, the IDA protocol achieved 92.2% synchronization between anisotropic α‐grain boundary (GB ...
