Abstract：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.
