Synergy of Strength and Plasticity in Extruded VZ91K Magnesium Alloy Achieved by Constructing Bimodal Grain Structure via Suppression of PSN‐DRX

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Bimodal grain structure (BGS) demonstrates significant potential in synergistically optimizing the strength and plasticity of magnesium alloys. Acquiring the desired BGS consequently became a critical challenge. This study took the Mg‐9Gd‐1Zn‐0.5Zr (wt%, VZ91K) alloy as its subject. From the perspective of BGS formation mechanisms, it suggests

含裂纹球壳裂纹尖端应力应变场及应力强度因子计算

, 1987
本文将“局部-整体分析法”(Local-global analy sis)推广到含裂纹球壳的断裂分析中,给出含裂纹球壳裂纹尖端应力应变场包括Ⅰ,Ⅱ,Ⅲ型的一般解.它类似于平面断裂问题中Williams展开式的作用,揭示了裂纹尖端附近的力学性质,为进行含裂纹球壳断裂分析提供良好的基础.平面断裂问题分析中一整套成熟的分析方法,诸如能量法,边界配置法,摄动法,有限元法等都可以移植到球壳的断裂分析中去.

Strength–Ductility Balance in Additively Manufactured Laminated Fe‐Cr‐Ni/Fe‐Cr‐Ni‐Cu Alloy Heterostructures

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Fe‐Cr‐Ni‐Cu alloy has been extensively utilized over the past few decades due to its low cost yet high strength. Nevertheless, the poor ductility of this alloy limits its real application in industrial fields. In this study, a soft Fe‐Cr‐Ni alloy was combined with a Fe‐Cr‐Ni‐Cu alloy by laser‐directed energy deposition (LDED) to fabricate the ...

Electric Field‐Induced Dark Current Steering in MAPbI3/Nb2CTx Photodetector Toward Weak‐Light Single‐Pixel Imaging

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT In conventional photoconductive detectors, the shared collection path for dark current and photocurrent imposes a fundamental compromise between noise suppression and signal responsivity. To break this trade‐off, we introduce a device architecture featuring a strategically integrated third electrode within a MAPbI3/Nb2CTx heterostructure. This

KW4系列空气断路器瓷瓶应力研究

Gaoya dianqi, 1981
对KW 4系列空气断路器在各种负载作用下瓷瓶的应力状态作了试硷研究,测出了瓷瓶各部位的静态及动态应力分布,并就静态应力作了计算对比。还仔细地研究了断路器不同整体结构对瓷瓶应力的影响,从减小瓷瓶应力角度出发,对断路器整体结构提出了修改意见。

Chloride Coordination‐Engineered Fe–NC Catalyst for Directed Singlet Oxygen Generation Through Peroxymonosulfate Activation

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Heteroatom coordination regulation is an effective strategy to enhance Fenton‐like catalysis of single atom catalysts, yet its impact on the local microenvironment of active sites still requires in‐depth investigation. Herein, Cl2–Fe–NC catalysts with axial Cl coordination are prepared.
