摘      要：The retained austenite content(RAC),the mechanical properties,and the resistance to cavitation erosion(CE)of the00Cr13Mn8Mo N steel after quenching and partitioning(Q&P)processing were *** results show that the Q&P process affected the RAC,which reached the maximum value after partitioning at 400°C for 10 *** tensile strength of the steel slightly decreased with increasing partitioning temperature and ***,the elongation and product of strength and elongation first increased and then *** sample partitioned at 400°C for 10 min exhibited the optimal property:a strength-ductility of 23.8 GPa?%.The resistance to CE for the 00Cr13Mn8Mo N steel treated by the Q&P process was improved due to work hardening,spalling,and cavitation-induced martensitic transformation of the retained austenite.
