| 摘 要： | 对管线钢室温分别在H2S NACE溶液和H2S 人工海水溶液中的氢致开裂进行了研究。管线钢在NACE试验介质中发生了氢致开裂(HIC)，沿夹杂物／基体界面及轧制方向的(珠光体 铁素体)带状组织导致了台阶状裂纹；而其在人工海水中则对HIC不敏感。为了提高管线钢的抗氢致开裂性能，应控制带状组织形态和级别。

| Abstract: | The hydrogen induced cracking (HIC) behavior of pipeline steels in H_2S+NACE solution and in H_2S+artificial seawater solution has been investigated.The phenomenon of HIC happened in NACE solution (5%NaCl+0.5%acetum,pH=3.5),and the banded structure (P+F) along the interface of inclusion/substrate and the rolling direction induced stepwise cracking.However,the pipeline steel was insensitive in artificial seawater solution and had no HIC.The configuration and grade of banded structure should be controlled to improve the HIC-resistant property of pipeline steels. |
