长时运行过热器12Cr1MoV钢管的内壁氧化层OA
The inner wall oxide layer of 12Cr1MoV steel pipe for long-term operation of superheater
采用扫描电镜分析、能谱分析、X射线衍射分析、透射电镜分析、X射线光电子能谱分析、力学性能测试等方法对长时运行过热器12Cr1MoV钢管的内壁氧化层进行研究.结果表明:高温服役条件下,12Cr1MoV钢管的晶界析出面心立方结构的Cr23C6 碳化物,该碳化物呈弥散分布,使晶界得到强化;钢管基材与内壁氧化层界面未出现明显的分层现象;随着服役时间的延长,晶界Cr23C6 碳化物呈链状聚集分布,碳化物逐渐增多,颗粒尺寸逐渐增大,氧化层组织疏松,且与金属基体之间存在明显的分界面.
Scanning electron microscopy analysis,energy spectrum analysis,X-ray diffraction analysis,transmission electron microscopy analysis,X-ray photoelectron spectroscopy analysis and mechanical performance testing were used to study the inner wall oxide layer of 12Cr1MoV steel pipes for long-term operation of superheaters.The results show that under high temperature service conditions,Cr23C6 carbides with a face centered cubic structure were precipitated at the g…查看全部>>
