Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Additive manufacturing of zinc‐magnesium (Zn‐Mg) alloys via laser powder bed fusion (LPBF) has gained significant recognition as a promising candidate for bone repair. However, the presence of coarse yet brittle eutectic phases in the fabricated Zn‐Mg alloys tends to induce premature stress concentration and resultant fracture during ...

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT TiN films deposited by physical vapor deposition (PVD) are widely used as protective films due to their high hardness and wear resistance. However, their application under high‐load conditions is limited by poor load‐bearing capacity and susceptibility to spalling on soft substrates.

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT In laser‐directed energy deposition (LDED) of TiC/Ti6Al4V composites, a low content of micron‐sized TiC provides a good strengthening effect on hardness and strength, but the improvement in plasticity remains a challenge. By introducing synchronous ultrasonic impact treatment (UIT) into the LDED process, an ultrasonic‐assisted LDED (UA‐LDED ...

Zhongguo cuzhong zazhi, 2022 院前延迟是急性缺血性卒中患者错过再灌注治疗时机的主要原因，常因患者不合理的就医行为决策导致。既往研究多探讨就医延迟、转运延迟等外在影响因素，较少从患者自身决策的角度进行院前延迟的分析。本文从缺血性卒中患者就医行为决策的概念、现状及其影响因素这3个方面进行总结，分析目前急性缺血性卒中患者就医行为决策中存在的问题，讨论认知、环境、心理等因素对患者就医行为决策的影响及原因，为制订针对性的干预措施提供参考。 Abstract: Pre-hospital delay is the main cause ...

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT The limited crack resistance of coarse grain boundaries and coarse interfaces leads to an incompatibility between high‐temperature strength and ductility in TiAl alloys. Tailoring stress‐oriented textures and multiscale heterogeneous interfaces can effectively impede crack propagation, thereby overcoming this trade‐off.

Guangtongxin yanjiu, 2020 针对两对被时间延迟分开的脉冲会根据相位和时延的变化影响脉冲间的传输特性,且在脉冲重叠区域会受到交叉相位调制的影响发生干涉现象的问题,文章提出了在色散渐减光纤环镜中观察脉冲对的传输特性,研究结果表明,可根据脉冲对之间的相位和时延变化,观察脉冲对的时域特性和啁啾特性,分析脉冲对在不同情况下的传输特性。

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT To overcome the challenges of the strength‐ductility trade‐off in laser additively manufactured (LAM) titanium alloys, and to avoid the intragranular microstructure degradation often caused by an exclusive focus on grain equiaxialization, this work proposes a novel strategy of “grain morphology‐intragranular microstructure co‐optimization ...

Jianzhu Gangjiegou Jinzhan, 2008 本文对中、日、欧州及美国地震规范地震力计算的结构影响系数的构成进行了分析,认为,美国的结构影响系数中包括了材料的强屈比、超静定结构体系的超强系数以及延性系数;而欧洲的结构影响系数包含了延性系数,对于延性好的结构还允许包含结构体系的超强系数;日本仅包含延性系数;我国也是仅包含延性系数。由于日本采用允许应力设计,还有一个1.4的安全系数,因此比较起来,日本的地震力最大。从结构影响系数的构成看结构在地震作用下产生塑性变形的深度,按照美国规范设计的结构塑性变形要求最高,欧洲次之,我国再次之 ...
