Dianci bileiqi, 2021 因生产中使用的灰蓝釉配方均采用锆系釉,具有高温粘度大,烧成温度高的特点;而坯料烧成温度低,产品烧成温度不能太高,造成灰蓝釉产品因烧成温度低而出现窑后流痕、缩釉,桔釉、表面不平整等现象,影响产品的外观。所以,需研制与坯料烧成温度匹配的低温电瓷灰蓝釉配方。

Jianzhu Gangjiegou Jinzhan, 2017 利用经试验验证的有限元模型对均匀温度和不均匀温度分布下轴向约束波纹腹板梁的悬链线效应进行了参数分析,选取荷载比、轴向约束刚度比、跨高比及倾角为主要参数,研究了钢梁的跨中挠度、梁端轴力和悬链线弯矩等随温度的变化规律,并给出了火灾下钢梁的临界温度。由于不均匀温度下产生的热弯曲,钢梁在压力阶段的挠度更大而轴力更小。但均匀温度下钢梁的破坏温度比不均匀温度情况时高。钢梁的悬链线温度和破坏温度都随着荷载比的增大而降低。相同荷载比作用下,不同跨高比钢梁的悬链线温度相同,但其破坏温度随跨高比的增大而升高 ...

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.

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

, 1993 【摘要】1.小容積の堆肥化反応解析装置を試作した.堆肥化反応槽には真空断熱壁を有するステンレス製容器を用い，さらにウォターバス温度を有機質資材温度よりも常に1℃以内で低くなるように制御することによって，小容積ながら実用規模の実験と同様な温度履歴が得られるようになった.この装置により少量の材料で堆肥化実験が可能になり，実験も格段に多く行なえるようになった.2.
