| 摘 要： | 首次采用原子力显微镜（ＡＦＭ）对Ｃｕ－Ｚｎ－Ａｌ合金中的马氏体浮突和贝氏体浮突进行了定量观测。在此基础上，将ＡＦＭ的测量结果与马氏体相变表象理论（ＰＴＭＣ）进行了对比，发现马氏体浮突角与ＰＴＭＣ理论相符合，而贝氏体浮突角与ＰＴＭＣ理论不符合，说明贝氏体相变机制与马氏体不同，不可能是切变机制；同时发现贝氏体浮突是一组贝氏体亚单元所造成的浮突组成的浮突群

| Abstract: | Surface reliefs accompanying martensite and bainite transformation in Cu Zn Al alloy have been investigated with atomic force microscopy (AFM) quantitatively. The phenomenal theory of martensite crystallography (PTMC) was applied to examine the surface relief angle obtained by AFM and agreeable results of martensite are available, however, the results of bainite are different from PTMC, indicating a non shear mechanism of bainite. Also, the inner structure of surface relief with martensite and bainite were investigated. |
