根据BS7448断裂韧度试验标准,对常用的E43厚钢板进行了CTOD(裂纹尖端张开位移)断裂韧度试验,分别测试了在20℃室温条件下母材、热影响区、焊缝区的CTOD数值,测试验结果表明:母材、热影响区、焊缝区的CTOD特征值均大于允许值,工程结构断裂韧度符合要求.

In accordance with the BS7448,fracture toughness test standard,CTOD（crack tip open displacement） fracture toughness tests were conducted for the heavy plate E43 at room temperature 20℃.The CTOD values of the base metal,heat effect zone and welded seam were obtained.The results show that their CTOD values are more than the allowable values,the str...
