摘　　要：研究了０～１０％的应变时效对１４ＭｎＶＴｉＲｅＡ钢薄板的强度、塑性及低温韧性和脆性转变温度的影响，结果表明，１４ＭｎＶＴｉＲｅＡ钢薄板的应变时效敏感性较低，时效后仍具有较好的韧性和止裂能力，可满足产品无限航区的使用要求。The effect of 0～10% strain ageing on the performance of 14MnVTiReA thin plate steel has been studied which includes strength, ductility, low temperature toughness and brittle transition temperature. As a result, 14MnVTiReA thin plate is less sensitive to strain ageing, and after aged,the plate still has good toughness and good ability of arresting cracks. So it is able to meet the service requirement of ship in unlimited area.
