| 摘 要： | 采用夏比冲击、裂纹源落锤和动态撕裂试验，研究了１０ＣｒＮｉ３ＭｏＶ钢的低温韧性，对韧性较高的原因也进行了分析讨论。结果表明：冲击曲线的上平台转变温度在－２０℃以下，韧脆转变温度ＥＴＴ５０和ＦＡＴＴ５０在－１１０℃以下；ＴＮＤＴ低于－７０℃，－４０℃的动态撕裂能在１０００Ｊ以上。 |

| Abstract: | The low temperature toughness of 10CrNi3MoV Steel is studied through Charpy impact test, drop weight test and the dynamic tear test. The reason that the steel has a good toughness is also analyzed and discussed. The result indicate that the steel has good toughness with its upper plateau temperature below -20℃, brittle toughness transition temperature ETT 50 and FATT 50 below -110℃, nil ductile transition temperature T NDT below -70℃ and dynamic tear energy at -40℃ above 1000J. |
