摘　　要：This paper proposes a direct and simple method to identify the second twins from twinning variants by electron back scattered diffraction （EBSD）. To clarify the orientation relationship between the neighboring crystals, the misorientation calculation by MATLAB software based on the EBSD data is also used. This method is generally applicable to predict the variants occurring in the nucleation and growth of the recrystallization or phase transformation process.This paper proposes a direct and simple method to identify the second twins from twinning variants by electron back scattered diffraction （EBSD）.
