| 英文摘要 | In order to understand the effect of Mo element on the high-temperature fatigue behavior of 15CrNbTi ferritic stainless steel, the stress-controlled fatigue tests have been performed for both 15CrNbTi and 15Cr0.5MoNbTi ferritic stainless steels at 800 degrees C in laboratory air. The fatigue test results indicate that the fatigue resistance of 15Cr0.5MoNbTi steel is manifestly higher than that of 15CrNbTi steel at the maximum stress below 57 MPa; the 15Cr0.5MoNbTi steel possesses a fatigue limit of 35 MPa, which is higher than that of 15CrNbTi steel. The TEM observations reveal that the Mo element can suppress the formation of coarsened Fe3Nb3C precipitates and result in the fatigue resistance enhancement. The dislocation networks formed during the cyclic load favor to improve the fatigue resistance of 15Cr0.5MoNbTi steel at 800 degrees C. |
