摘要

采用氧化增重法研究了高硼奥氏体钢在850℃下的高温抗氧化性能

采用SEM和XRD研究了其氧化产物的组织形貌与相组成

分析了B对材料高温抗氧化性能的影响。结果表明

添加B后

B在奥氏钢高温氧化测试中形成了致密的硼酸盐氧化膜

提高了钢的抗高温氧化性能。在850℃保温20h后的氧化增重速度由不含B的4级"弱抗氧化性"提高到2级"抗氧化性"

且奥氏体钢高温抗氧化性能优于ESR-H13钢的5级"不抗氧化性"。

Abstract

Effects of boron content on the high-temperature oxidation resistance of high-boron austenite steels at 850 ℃ were investigated by oxidation weight increase method

and microstructure and phase constituent of oxide products were analyzed by SEM and XRD.The experimental results show that the boron can increase high-temperature oxidation resistance of the tested steels through forming compact oxidized film.The high-temperature oxidation resistance properties after adding boron is increased from grade 4to grade 2according to the oxidation resistance standard in GB/T 13303-1991

much better than grade 5of ESR-H13 steel for comparison.
