摘要
利用金属物理实验方法，研究了在线常化工艺对Ｎ８０钢管组织和性能的影响。结果表明，在线常化工艺可以在适当减小强度值的情况下大幅度提高钢管的冲击韧性，尤其可使微合金化钢获得较好的强韧化效果。
Used the research method of metal physics, the influence of on-line normalizing to structure and properties of N80-tube has been researched. The results show that the tenacity of tube can be improved by a large margin when the strength be decreased a little. What is more, it has a good strength and tenacity can be get by microallying
