石油焊管用低碳微合金化钢的强韧化途径

To Increase The Toughness of Low Carbon Micro-alloying Steel Used by The Oil Welded Pipe

结合石油焊管用低碳微合金化钢的研制开发，从合金化、冶炼、控轧工艺以及形变热处理等几个方面分析论述了钢的强韧化途径，同时结合组织形态观察，阐述位错强化、弥散强化、析出强化等冶金措施在石油焊管用钢中的作用。

Combined with researching and developing of low carbon micro-allying steel used by the oil welded pipe, the article describes and analyses toughness means of steel from alloying, smelt, control rolling and deformation heat treating, etc. It also introduces that the function of increasing, disperse increasing, separate increasing etc. used in the oil welded steel.
