本文通过插销断口分析,研究了含硼12Ni3CrMoV钢焊接热影响区氢浓度及应力大小与断口形态之间的关系,结果表明,插销断口具有氢脆准解理特征,断口上氢脆准解理区域随氢浓度的升高而增加,随负载应力的加大而减小.准解理断裂面为{110}面.
A fracture analysis on an implant made of steel 12Ni3CrMoV containing 6ppm B was carried out of the dependence of the fracture morphology of hydrogen-induced cracking upon the hydrogen content in HAZ and upon the stress applied.It was shown that its fracture is of the quasi-cleavage(QC)crack of hydrogenembrittlement Its QC region on the fracture surface may be broadened ornarrowed with the increasing of the hydrogen content or the applied stressrespectively.The crystallographic orientation of the QC cracking in HAZ wasverified to be{110}plane by means of the etch-pit method.
