中文摘要：

电子背散射衍射（EBSD）技术能够定量分析晶体材料形变显微组织。本文比较了EBSD数据的不同处理方法在分析形变显微组织中的应用效果,讨论了用局部取向梯度和取向离均差研究形变组织的微观分析方法。尝试用Matlab软件对EBSD的原始数据进行处理,重构出单个晶粒的相对全Euler角图,能很好研究单个晶粒内的形变显微组织。

英文摘要：

The electron backscatter diffraction（EBSD） technology offers crystallographic data to analyze deformed microstructure qualitatively or quantitatively.Several EBSD data processing methods were used to study the low strain level microstructure in this paper,and the local orientation gradient and the deviation from an average orientation were applied to describe the deformed microstructure quantitatively.Matlab was used to reconstruct relative all-Euler map based on the raw EBSD data.The relative all-Euler map was a good method to study the deformed microstructure inside a single grain.
