Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT This study demonstrates a new strategy for modifying the boron content to address stress‐relief cracking (SRC) in the 7CrMoVTiB10.10 alloy. First, coarse‐grained heat‐affected zone (CGHAZ) specimens with different boron contents were prepared via simulated welding thermal cycles.

Drawing up shear stress-strain graphs of the mild steel in high temperature [PDF]
, 1955 P. H. Kaar published the paper treating a method of obtaining shear stress-strain graphs by interpretation of moment-twist data in Trans. of the ASME, May, 1953. The author tested the torsion of the carbon steel (c=O.26%) in high temperature -- 300℃, 400℃

工程建设高温空气燃烧技术的应用，不仅可以提升工业炉内部的燃烧效率，而且可以减少污染物的排放。燃烧的温度越高，产生的热量越多，说明燃烧的越充分。窑内的温度越高，烟气中CO、CxHy、H2的含量也会大大增加，之后降低，循环这样的过程。文章围绕高温空气燃烧技术，论述隧道窑中燃烧技术的应用，并提出相应的改造措施，仅供参考。

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Laser powder bed fusion (LPBF) can fabricate high‐entropy alloys (HEAs) with refined microstructure and enhanced mechanical properties. However, the deformation and fatigue mechanisms of Al‐containing HEAs produced by LPBF remain unclear. In this work, we systematically investigate the tensile properties, deformation mechanisms, and high‐cycle

Sexuality, Gender &Policy, Volume 9, Issue 2, May 2026.ABSTRACT Masculinity significantly influences men's health‐seeking behaviors, yet its intersection with legal frameworks and healthcare access in Sub‐Saharan Africa remains underexplored. This mixed‐methods study investigates how gender norms and structural barriers influence healthcare experiences among 60 middle‐aged men (aged 30–60 years) in Yaoundé,

Studies on Heat Tolerance in Abalone Based on the Measurement of Heart Rate [PDF]
, 2016 鲍是海产八珍之首，2015年，我国的鲍产量已经超过13万吨，其中福建省的产量占全国的80%。皱纹盘鲍为温带种，原分布于我国黄、勃海海域，1990年代后期南移福建后，获得了极大发展，由此福建逐步成为我国鲍养殖的主产区。但福建海域的夏季高水温往往导致鲍的高死亡率，这一直困扰着鲍养殖产业的发展。因此，培育耐高温的养殖新品种显得格外重要，而其中建立鲍的耐高温性状的准确测评方法是品种培育的关键。本研究中，我们通过测定阿氏拐点温度（Arrheniusbreakpointtemperature，ABT ...

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Nickel‐based superalloys (Ni‐based superalloys) have attracted extensive attention in laser additive manufacturing (LAM) due to their capability to directly fabricate complex and high‐performance structural components. However, the rapid melting and solidification inherent to LAM result in intense thermal cycling, which induces high residual ...

Jianzhu Gangjiegou Jinzhan, 2011 基于火灾高温下空间网格结构的性能,本文根据欧洲规范了中高温下的钢材特性和国际标准升温曲线（ISO834）,对单轴受拉焊接空心球节点高温下的性能进行了数值模拟,分析了空心球的温度场分布规律和极限耐火时间的影响因素。通过分析高温下空心球的应力和位移变化特征,确定了其破坏模式;结果表明钢管根部和赤道处是其高温下受拉承载力的薄弱环节。

Jianzhu Gangjiegou Jinzhan, 2021 冷成型钢构件在经历火灾(高温)后,力学性能可能发生衰减,需要关注其承载力的变化并做出准确评估。因此,在现有高强冷成型钢过火后材性与构件测试结果的基础上,通过数值仿真模拟预测构件经历不同温度后的力学行为。通过参数分析,开展开口截面承压构件过火后性能分析,研究高温后的构件长细比、截面形式对承载力和破坏模式的影响,评估常温构件设计方法的适用性。有限元建模和参数分析的结果表明:(1)冷成型钢构件材性的衰减不是影响其过火后性能的唯一因素,在特定温度段须考虑重量折减;(2 ...
