Dianci bileiqi, 2019 机械强度属于盘形悬式绝缘子的重要指标,但在机械试验中会出现盘形绝缘子形变。为研究机械试验过程中各部件的承力及形变情况,本文以120～550 kN的盘形悬式瓷、玻璃绝缘子为研究对象,以金属材料弹性模量计算方法为基础,开展了盘形悬式绝缘子的应力应变特性研究。研究表明,盘形绝缘子形变主要集中在铁帽和钢脚处,其前期的弹性模量受到铁帽形状设计的影响,其形变值大于铸铁材料形变值的10倍;根据Inglis理论和Griffith能量平衡理论,尽管水泥碎裂产生的势能释放有一部分由沥青的缓冲 ...

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT A synergistic strategy combining a Ti interlayer and circular beam oscillation was proposed to improve the laser weldability of 6082‐T6 aluminum alloy. The Ti interlayer suppressed porosity, eliminated columnar grains, and significantly reduced grain size by 67.7% at the weld center. Mechanistically, fine L12‐Al3Ti precipitates clearly showing

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Microstructural characterization of Li0.32La0.56Fe0.01Ti0.94Sb0.06O3 (LLFeTSO) using AC‐TEM revealed that Fe3+/Sb3+ ion co‐doping induces the migration of lattice oxygen to grain boundaries (GBs), enhancing GB conductivity. However, the atomic arrangement at the GBs remains highly ordered and lacks sufficient cation vacancy carriers.

Jixie chuandong, 1998 本文利用两个梯形来模拟渐开线直齿齿廊，导出了适合联轴器轮齿变形的计算公式。由于直齿联轴器内，外轮齿接触的特殊性，在以往计算基于外啮合轮齿变形的当量齿形法中，Ｈｅｒｔｚ接触变形将不适合，而应代之以材料的整体压缩变形。最后本文运用数值计算，并与用有限元法计算的值进行了比较，结果非常接近。

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Overcoming the strength–ductility trade‐off in face‐centered cubic (FCC) multi‐principal element alloys (MPEAs), particularly at cryogenic temperatures, remains a significant challenge. Here, a laser powder bed fusion (LPBF)–enabled direct aging strategy is employed to modify the precipitation behavior in a Ni53Fe20Cr23Nb4 (at%) alloy.
