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
For the first time, atomic force microscopy (AFM) was used to quantitatively observe martensite buoyancy and bainite bump in Cu-Zn-Al alloys. On this basis, the results of AFM and martensitic transformation theory (PTMC) were compared and found that the martensitic buoyancy angle coincided with the PTMC theory, and bainite buoyancy angle and PTMC theory does not conform , Indicating that the mechanism of bainite transformation is different from that of martensite and it is impossible to be a shear mechanism. At the same time, it is found that the bainite bump is a group of bursts caused by a group of bainite subunits
