【摘要】 采用金相显微镜、扫描电镜和能谱仪等设备对连铸坯、锻坯和无缝钢管中产生的5例典型氢损伤缺陷(如白点、鱼眼、氢鼓泡等)进行了分析研究,论述了各类氢损伤缺陷的特征和产生原因。结果表明:钢中存在一定量的氢、成分偏析、夹杂物偏聚等因素是导致其产生氢损伤缺陷的主要因素。提出了改进措施。更多还原

【Abstract】 Five cases of typical hydrogen damage defects(such as flake, fisheye, hydrogen blistering, etc.) produced in continuous casting, forging and seamless steel pipes were analyzed using optical microscopy, scanning electron microscopy, energy dispersive spectroscopy and other equipment. Discuss the characteristics of various types of hydrogen damage and causes of defects. The results showed that: the major factors lead to hydrogen damage defects are a certain amount of hydrogen in steel, segregation and inclusions. We propose the corresponding solutions.更多还原
