Synergistic Enhancement of Creep Performance in Al19Co21Fe20Ni40 Eutectic High‐Entropy Alloy by Coupling Heterostructure Design With Boron‐Assisted Interfacial Optimization

open access: yesRare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT This study systematically investigates the creep behavior of an Al19Co21Fe20Ni40 eutectic high‐entropy alloy (EHEA) at 500°C, focusing on the synergistic effects of heterostructure design and trace boron doping. Thermomechanical processing was employed to produce a heterostructure consisting of alternating lamellar and equiaxed regions.

Decorating Graphite Felt Electrode With Uniformly M‐Nx Functionalized Carbon Nanosheets for High‐Performance Vanadium Redox Flow Batteries

open access: yesRare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT Vanadium redox flow batteries show considerable promise for energy storage, yet their overall performance is still hindered by the limited electrochemical activity of graphite felt (GF) electrodes. Herein, using folic acid and metal salts as precursors, M–N–C functionalized carbon nanosheets (M–NC, M=Co, Fe, and Ni) were prepared via a ...

Ultrasonic Spray Pyrolysis‐Derived LSCF‐GDC Nanocomposites as Durable Oxygen Electrodes for Solid Oxide Electrolysis Cells

open access: yesRare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT Solid oxide electrolysis cell (SOEC) technology is a promising route for efficient and clean green hydrogen production because of its high conversion efficiency and the use of precious‐metal‐free catalysts. However, developing oxygen electrodes that combine high electrochemical activity with robust long‐term operational stability remains ...

细瓷的新型溶剂

open access: yesDianci bileiqi, 1991
探讨了制备不溶于水而其软化及熔融性熊与天然长石相同的钾钠混合熔剂的可能性。其合成方法是把钾钠的碳酸化合物或氯化物在1500℃下熔融。熔剂样块呈白色,光滑有光泽无开口气孔。合成熔剂烧结范围宽,在1000℃烧成时即可形成基本的结晶相,在1200 ...
