STM Study on the Surface Relief and Mechanism of Bainite Transformation

Zhigang YANG , Hongsheng FANG , Jiajun WANG , Yankang ZHENG and Chunming LI(Dept. of Materials Science and Engineering , Tsinghua University , Beijing 100084 , China)

材料科学技术（英文）

Scanning tunneling microscopy (STM ) has been first employed to study the surface relief accompanying bainite transformation in a Fe-2.17C-12.18Cr-0.31Si-0.26Mn (wt pct) steel. With the exclusive vertical resolution of STM, we observed that the surface relief associated with bainite is a group of su...
