| Abstract: | In this paper,impact—toughness of 45CrMnSi steel is studied under two different heat treatment conditions.Series impact tests show that intercretical hardening near by the Acl can significantly improve the impact——toughness of the steel,and cold embrit- tlement transition temperature can be decreased. |
