摘要: 将经典的三维(3D)晶粒组织系列截面分析方法与EBSD有机结合, 以纯Fe为实验材料, 基于400幅纯Fe晶粒组织系列截面图像(每个截面图像包括约150个晶粒截面), 成功构建了集多重信息于一体的纯Fe材料中一组3D晶粒的数字化可视模型. 该类晶粒模型可供在3D空间从任意角度随意观察, 可定量反映单个晶粒尺寸、形状及拓扑特征等几何形态信息, 并可给出各晶粒及其晶界在3D多晶体空间中的真实取向信息.

Abstract：The informations of hree dimensional (3D) grain in real materials were rarely obtained directly, especially when the grain size, shape, topology and orientation were all required. By combining the classical serial sectioning and electron backscatter diffraction (EBSD) technique, a 3D digital visible model of a group of grains in a real pure iron specimen was constructed based on 400 parallel serial section images (about 150 grains appearing in each section image) with an average inter-section distance of (1.69±0.3) μm. The model presented enables the stereoscopic observation in a 3D space. Besides, this model can provide not only the quantitative geometric information including grain sizes, shapes and topological characteristics, but also the real orientation information of both the grains and their boundaries in 3D polycrystal space, which offers new insights into the digitalization and visualization of real material microstructures.

Key words： 3D reconstruction serial sectioning EBSD grain morphology crystallographic orientation
