| 摘 要： | 采用动态撕裂试验方法评定了CF-60钢焊缝、热影响区、母材的抗断裂性能,结果表明,这3个区域中焊缝的撕裂能和断口形貌的转变温度最低。同时,用统计方法分析了DTE-T试验结果并讨论了断口形貌准则。

| Abstract: | The dynamic tear test was used in the evaluation of the resistance to fracture of CF60 steel in the regions of the weld. HAZ and parent metal and the lowest transition temperatures of DTE-T and S_A%-T curves were obtained for the weld from the three different regions. Meanwhile the DTE-T_s were analysed by means of the statistical method and the fracture appearance criterion is discussed also in this paper. |
