利用电子显微分析（TE）和ODF织均分析，研究了纵横轧制铝板再结晶退火前后的织构和再结晶过程．直接观察到再结晶过程中的选择长大，经电子衍射分析了新晶粒的取向，并通过极图分析了各织构组分＜111＞间的关系结果表明，纵横轧制铝板再结晶过程中存在选择生长现象，并最终决定再结晶织构；面心立方金属中这种取向关系约为40°＜111＞
The microstructures and textures during recrystallization process in the aluminium sheet which had been longitudinally and transversely rolled were investigated. The oriented growth during the recrystallization was directly observed by transmission electron microscope and the orientation relationships of new grains were determined by electron diffraction. The pole figures were measured with X-ray diffraction goniometer and ODF's were calculated by Bunge's method. The results showed that recrystallized grains with some oriented relationship to the deformation matrix grew more rapidly than others, which leads to the final texture. In fcc metal, this orientation relationship is about 40° <111>.
