hot brittleness

The curve of loading and deformation veried that bamboo and wood composite plywood mainly showed low-temperature brittleness and hot brittleness when treated in cold water, frozen condition, and drying.

负荷挠度曲线表明，竹木复合胶合板在冰冻、冷水、干热下表现为脆性破坏为主，热水处理时的性能变化表现出粘弹性为主的特征，竹木复合材料的静态力学性能表现与其粘弹性变化机理相关。

The hot brittleness mechanism and structure of surface oxide coating of low-alloy steels containing 0. 3%-0. 7% of copper have been investigated by means of hot/ cold bending tests, optical microscopy, SEM and EPMA.

用冷、热弯试验及光学显微镜、扫描电子显微镜和X射线微区分析仪分析研究了含0.3%～0.7%Cu的低合金钢表面氧化层结构及热脆机理。

Not only it generate hot brittleness, also it can cause much negative impact on hot-working character, mechanical property, welding performance, resistant character, processability and cold-heading.

硫不仅能引起钢的热脆，而且对钢的热加工性能、力学性能、焊接性能、耐腐蚀性能、成型性以及冷镦性能都有很大的负面作用，所以脱硫一直是冶金工作者研究的重点之一。
