Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Laser powder bed fusion (LPBF) of Inconel 718 alloy inevitably introduces pronounced microstructural anisotropy, typified by columnar grains and robust crystallographic texture. This results in direction‐dependent fatigue behavior, raising critical reliability concerns for high‐stakes aerospace applications.

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT In this work, In2O3 and three rare earth (RE)‐doped In2O3 composites (Ho, Yb, and Sm‐doped) were prepared via the hydrothermal method. Compared with In2O3 sensors, those fabricated from the three composite materials (RE–In2O3) exhibit varying degrees of enhanced response toward ethylene glycol (EG) gas. At 35% relative humidity (RH) and 250°C,

Dianci bileiqi, 2022 笔者针对钢结构变电站直击雷防护，对雷击过程中变电站接地特性进行研究，相较于通过避雷带引下线接地的现行方案，在采用钢柱直接接地情况下，地表电位升最大值下降幅度达到26.5%。钢结构变电站的导体网络对于具有大量高频分量的雷电流具有明显的电感效应，地表电位升峰值时刻超前于雷电流约5μs。雷电流散流集中于注流点附近的4～5条引下线或者连接线，总散流占比超过90%,相比现行方案，通过钢柱接地的方案散流更加集中于注流点附近的4条连接线，距离注流点最近的连接线分流占比达到了55.19 ...

Dianci bileiqi, 2009 探讨了发电厂、变电所因地电位分布不均对计算机综合自动化系统造成的影响,即在雷电流入地时冲击电位分布造成的干扰,在工频大电流入地时由局部电位升高造成的干扰,以及变电站内发生接地短路时造成的电弧干拢。分析了地电位干扰产生的原因,针对干扰的途径及方式提出了防止地电位干扰的具体措施:降低接地网的接地电阻,限制地电位升高;设计接地网时应尽量采用方孔地网以改善地面电位分布,限制局部电位升高;改进计算机测控系统的接地;计算机测控系统应屏蔽接地;以保证变电站的安全稳定运行。
