摘　　要：电子背散射衍射(EBSD)是一种用来分析多晶材料显微结构和组织的扫描电子显微镜技术,近年来已经被广泛应用于不锈钢材料的分析,对其晶界类型、织构、位向差和相结构等进行观察。结合不锈钢研发和生产过程中遇到的实际问题,介绍了EBSD技术中的一些功能在解决应力分布、相结构关系的表征、相鉴定、晶界类型及其分布、织构分布、真实晶粒度测定等方面的应用。Electron back-scatter diffraction （EBSD） is a scanning electron microscope-based technique used to characterize microstructures and textures in polycrystalline materials. This technology has been widely used in the analysis of stainless steel these years and the grain boundary, texture, misorientation and phase structure can be observed by EBSD technology. Some of the functions have been introduced by using actual cases in the process of the stainless steel production and research, it can solve the problems of stress distribution, phase structure characterization, phase identification, grain boundary distribution, texture distribution, real grain size measurement and 80 on.
