慢速热循环对铬钼钒铁素体耐热钢蠕变性能的影响

摘要

试验测定慢速热循环对CrMoV铁素体耐热钢(0.16C-1.35Cr-1.02Mo-0.26V)蠕变性能的影响。结果表明，用Dorn和Miller两种外推法来预测这种钢在循环温度下的性能是可靠的。%The effect of slow thermal fatigue on Cr|Mo|V ferrite heat resistance steel (0.16C|1.35Cr|1.02Mo|0.26V) has been experimentally measured. The test results show that it is reliable to predict the creep property of this steel under thermal cycle by Dorn and Miller extrapolation of creep data.
