摘要：
This paper dealt with the influence of quenching temperature for dual phase zone on the mechanical properties and transformed structure of 5NiCrMoV steel and their relationship. The rule for determining optimal quenching temperature for (α+γ) dual phase zone was put forward. The results show that the toughness and ductility of the steel after strengthening and toughening are remarkably increased and the brittleness transformation temperature is notably decreased. This is a new way to improve the toughness of tempered steel.
