摘要
介绍了钢铁材料强化方式的发展历程,对超细晶粒钢的制备工艺和冶金机制进行了详细阐述。比较了传统TMCP与新型TMCP的异同,总结了目前采用的细化晶粒低温大变形方法的两种机制。分别简单介绍了鞍钢、本钢、攀钢和宝钢中超细晶粒钢的生产工艺及应用情况。
The developmental process of the ways of strengthen for steel materials was introduced.The manufacturing technologies and metallurgical mechanisms of UFG steels were specified.The differences between conventional TMCP and new type TMCP were compared,and two mechanisms of low temperature large deformation for fine-grained were summarized.The producing technologies and applications of the Ultra fine-grained （UFG） steels in Anshan Steel Company,in Benxi Steel Company,in Panzhihua Steel Campany and in Baoshan Steel Company were simply illustrated respectively.
