| Abstract: | Microstructure and mechanical properties of the X4CrNiCuMo14-5 blade steel after solution treatment, intermediate adjustment treatment followed by aging at different temperatures have been investigated by XRD,OM and SEM.The results show that the hardening effect of aging at 450 ℃ is the most significant,whereas the austenite recrystallization will occur in aging at 660 ℃,leading to decrease in the retained austenite content and increase in the strength of the steel. |

| Keywords: | aging mechanical property retained austenite X4CrNiCuMo14-5 blade steel |
