原子力显微镜在马氏体相变浮突研究中的应用

Application of Atomic Force Microscopy on the Study of Surface Relief Accompanying Martensitic Transformation

用原子力显微镜在大气环境中对Fe－Ni－C合金中的马氏体浮突进行了观察和定量测量。结果表明，原子力显微镜既可清楚地观察浮突形貌，又可定量测量其高度和形状变化，从而提出了一种研究相变浮突的新方法。

This paper presents the study of surface relief induced by martensitic trans formation in Fe-Ni-C al-loy with atomic force microscopy(AFM)- The results show that AFM provides both morphology and the heightinformation of surface relief, therefor AFM is proved to be a new powerful method for investigating surface re-lief.
