It was discovered that the surface relief due to Widmanstatten ferrite formation appears to be of tent-shaped type, or complex type.The evolution of surface relief of Widmanstatten ferrite can be more interpreted by ledgewisegrowth mechanism rather than by displacive mechanism. The height of relief is 70-450 nm, and the maximum shape deformation is ca. 0.36. Key words： surface relief    Widmanstatten ferrite    scanning tunneling microscopy    shapede formation 收稿日期: 1998-04-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 薄祥正 方鸿生 王家军 王峥华 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1998/V34/I4/345 1 Christian J W.
