摘要
用离子探针研究了１０ＳｉＭｎＮｉＣｒ钢不同焊接条件下氢在焊接接头负载缺口顶端的再分布，发现近缝区开裂方向有两个氮浓度富集峰。并探讨了双氢峰的形成机理。
Redistribution of hydrogen concentration in welded seam zone of 10SiMnNiCr near notch tip under mixed mode loading has been studied by Ion Microprobe. It is discovered thatthere exist two accumulation peaks of hydrogen conentration,one at notch tip and the other far apart frorn it,in the cracking direction of welded seam zone. The mechanism of hydrogen accumulation near notch tip was also discussed.
