- 摘要:
- 实验得到了1种抗氧化性能较好的高硼双相耐热钢材,并研究了其氧化层结构与氧化动力学。结果表明,实验所得钢材在750℃下的抗氧化性能达到GB/T 13303-1991《钢的抗氧化性能测试方法》中的1级“完全抗氧化性”标准,其基体为铁素体/奥氏体双相,增强相为硼化物。其氧化动力学曲线在实验前10 h遵循直线规律,10 h后遵循对数规律。
In this study,the high-temperature oxidation resistance properties of high-boron dual-phase steels were studied.The experimental results showed that test steel meets the level of“complete oxidation resistant”according to Chinese National Standard GB/T 13303-1991“steels-determination method of oxidation resistance”.For the 100-hour-oxidation-experiment at 750℃,test steel gradually formed a thin but dense oxide layer,which can prevent the steel from further oxidation.At the beginning 10 hours of the experiment,the oxidation kinetics curve obeys the law of straight line,then the oxidation kinetics curve obeys the logarithmic law.
