摘要
用离子探针测定了１０ＳｉＭｎＮｉＣｒ钢不同焊接条件下的焊接接头微区氢浓度分布，首次获得了真实的氢浓度分布图象。并讨论了氢在焊接接头的分布行为。
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.
