, 2013 以氯化钠作为共晶盐研究对象,探讨共晶盐反复多次的低温液-固相变后的晶体变化趋势。通过X射线衍射仪对试样相变前后的晶体的晶面间距、粒径等参数进行分析,判断其晶体结构的变化趋势。同时通过同步热分析仪、电导率仪分析试样相变前后的潜热、电导率的变化趋势。分析结果表明,共晶盐经过反复多次的相变后,晶体粒径从微米级逐渐向纳米级转变,有向无定形非晶体转化的趋势;同时,相变温度 ...

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Lithium‐rich manganese‐based cathodes (LRM) deliver high discharge capacities beyond 250 mAh g−1, but their practical deployment is restricted by irreversible oxygen redox, structural reconstruction, sluggish kinetics and unstable cathode‐electrolyte interfaces (CEI). Here, we develop a colloid‐assisted anchoring‐diffusion engineering strategy

Inverse Thermal Softening Behavior in a High‐Entropy Alloy Under Various Strain Rates
Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Although face‐centered cubic high‐entropy alloys (HEAs) have received extensive attention and in‐depth research, most existing studies focus on single temperature or strain rate conditions, lacking systematic investigations into deformation mechanisms under extreme thermomechanical coupling environments.

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Heterogeneous structures have demonstrated great potential for overcoming the long‐standing strength–ductility trade‐off in metallic materials. In this study, a novel dual‐gradient structure, characterized by gradients in both grain size and precipitate distribution, was successfully constructed in an Mg–2Zn–0.8Gd (wt%) alloy sheet via sliding
