Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT Powder metallurgy (PM) near‐α Ti alloys are often constrained by a pronounced strength–ductility trade‐off, due to the coarse lamellar microstructure formed during the sintering process. To address this issue, a thermomechanical route combining cyclic hot rolling with short‐time solution treatment was developed to improve the mechanical ...

Gaoya dianqi, 2011 输电线路导线覆冰不仅与微气象条件有关,而且与导线温度有关。针对目前微气象因素与覆冰的相关性分析不全面、不系统,且部分研究没有考虑导线温度对覆冰的影响,无法确定输电线路导线覆冰的主要影响因素等问题,笔者统计了贵州电网220kV铜黎线路和220kV鸡阳二回线路覆冰监测数据,采用灰关联方法分析了输电线路导线覆冰与微气象条件（环境温度、环境湿度、环境风速）和导线温度等因素之间的关系,确定了该两条输电线路导线覆冰和上述4个因素之间的关联度,找出影响导线覆冰的主要因素。结果表明 ...

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.
