| 摘 要： | 采用热模拟、透射电镜、电子探针及电子衍射等手段对微量元素Ti 在硅锰低合金钢中的作用进行了研究。结果表明:微量元素Ti 具有细化晶粒,阻止形变奥氏体的动态再结晶及沉淀强化作用;另外 Ti还能与钢中硫、锰作用形成粒状的复合夹杂物,从而提高了钢的冷弯性能。

| Abstract: | Effect of trace Ti on Si-Mn low-alloy steel was studied by mea-ns of thermal simulation, TEM, EPMA and electronic diffraction. The resultsindicated that the effect of trace Ti includes grain refining, precipitation har-dening and dynamic recrystallization preventable to deformed austenits. Further-more, a complex granular inclusion will be formed by Ti in combination withMn and S in steel,thus improving the cold-bending ability of the steel. |
