【摘要】 近年来,新开发的电子背散射衍射技术将多晶材料的显微组织、微区成分与结晶学数据分析联系起来,能对晶界类型、取向、位向差和结构及其分布进行观察、统计测定和定量分析,从而建立了晶界结构、取向和织构等与多晶材料性能的定量和半定量关系,成为现代材料研究的重要实验技术。笔者结合低碳钢生产中的一些实际问题,扼要介绍了电子背散射衍射技术中的晶体取向图在多晶材料显微结构表征中的应用。更多还原

【Abstract】 Electron back scattering diffraction (EBSD) is a new technology developed in recent years for material analyses on the microstructure, micro-component and crystal orientation. The quantitative and quasi-quantitative results of the interface structure, orientation and microtexture can be obtained by the observation on the intergranular type, orientation etc. Thereafter, EBSD has become a key experimental technique in modern material research. So the new technology of EBSD-crystal orientation mapping (COM) and its application in the research field of iron and steel production were introduced here.更多还原
