电子背散射衍射技术EBSD在测定晶体取向、显微织构及统计晶界结构参数等方面具有独特的优势，可统计分析晶体中晶粒大小和晶界结构。金属宏观性能与晶界结构联系紧密。本文综述了近些年用EBSD技术研究各类金属材料（如铁基、镍基、铜基、钛基等）晶界中取得的众多新进展，如发现重结晶可以使特殊晶界比例增高，小角度晶界与材料耐火性能之间有密切联系以及特殊晶界在动态破坏和疲劳中起着重要作用等。这些结果建立了材料晶界性质和宏观性能之间的联系，为金属材料性能判定提供参考，也为材料学研究提供新依据。

Due to the unique advantage on grain boundary misorientation and micro-texture,electron back scatter diffraction was usually used to analyze the grain size and boundary in crystals statistically.The macroscopical performance of metal was closely associated with grain boundaries.Recent processes on the grain boundary of a series of metals,such as Fe-,Ni-,Cu- and Ti-based materials,by EBSD were reported in the paper.It was found that recrystallization would increase the fraction of special grain boundary,low angle grain boundary was in xtricably inked with the fire resistance and special grain bound ry played an important role in dynamic damage and fatigue et al.These results established the connection between the properties of grain boundary and the macroscopical performance,providing a reference for performance deter-mination and new evidence for ma rial science.
