Effects of ta.content on microstructure and oxidation behavior of AlcoCrFeNiYta. high entropy alloy

引用

Rare Meta.s 2024年第9期43卷 4462-4475页

作者： Cang Gu Jun-Hao Hu Jian-Bo Song cheng Xu Ming-Yu Hu Yu-Xuan Zhang Jiang Tian Chao Li Jing Feng Faculty of Materials Science and Engineering Kunming University of Science and Technology Department of Physics Hong Kong Baptist University

The oxidation behavior of the Al co Cr Fe Ni Yta.high entropy alloy（HEA） doped with different ta.contents at 1100 °C is investigated. In this study, different reasons for the spallation of the oxide scales of HEAs without/with excessive ta.addition after 1000 h of oxidation are discussed, and the most suita.le ta.doping content for this HEA is explored, in which the HEA exhibits both an exceptionally low oxidation rate, and the formation of oxide scales composed of inta.t a-Al2O3. Meanwhile, it is found that the addition of ta.can effectively inhibit the phase transition of β phase, which makes the surface of the oxide scale smoother. By combining our experimenta. results with Wagner–Hauffe theory, the influence of ta.drag effect on oxide scale growth is explained, which provides some theoretical guidance for the subsequent design of Al co Cr Fe Ni HEAs, and can lead to the development of thermal barrier coatings at higher service temperature.

为研究飞机不同横滚角度下客舱火灾发展规律,利用PyroSim搭建国产单通道客机客舱火灾模型,通过分析客舱烟气层高度、温度、co体积分数变化,得到客舱及翼上出口处的可用疏散时间(ASET)。研究结果表明:影响客舱内部ASET的首要因素是温度,而影响翼上出口处ASET的则是co;飞机横滚会导致客舱火灾高温区域由同侧壁向客舱前后两端蔓延,导致温度纵向影响跨度增大,但高温区域面积减小;横滚姿态下飞机翼上出口处温度上升时间延后,且最高温度降低;横滚角度增大会使翼上出口处ASET增加,但对前后舱门处影响不明显。研究结果可为航空器横滚姿态下的火灾疏散提供一定参考。
