摘要
研究了五种材料在ＮＡＣＥ溶液中的氢致开裂（ＨＩＣ）行为。结果表明：当材料中存在带状组织时，ＨＩＣ敏感性增高。为避免带状组织及ＨＩＣ，要控制Ｍｎ、Ｐ含量。给出了Ｍｎ、Ｐ含量的推荐值：Ｍｎ≤１．３％，Ｐ≤０．０１６％。
The behaviour of Hydrogen Induced Cracking (HIC) was investigated into five kinds of material in NACE solution. The experimental result shown: sensibility of HIC was high with bandstructure. It should control content of Mn and P in order to avoid band structure and HIC. The recommended value of Mn and P content are given Mn≤1 3%, P≤0 016%.
