摘要
用透射电镜高温原位观察了β黄铜中贝氏体的应力诱发生长形态，并根据晶体学分析否定了这些形态为感应形核，发现了剪切应力场存在的证据．在初生贝氏体中发现存在层错亚结构．结果支持贝氏体的切变机制．
In SITU observation of the growth images by shear,inclucing Bainitic plate in β brass by means of hightemperature TEM is conducted.It is pointed out by analysis of crystallography that these images aren′t induction nucleus.It is found the evidence of shear stress field and the stacking fault substructure exists in initial α1 plates.The shear mechanism of Bainite transformation is supported by this investigation.
