中文摘要:
??????通过电子背散射衍射技术,测定了一种5083铝合金中的热轧织构。结果表明:在结构中的不同位置,织构组分呈现非均匀发展的特点,特别地,晶界面亦呈现取向织构。在样品的中心位置,晶界面趋向于{111}取向,且其数量高出随机晶界50%;同时,在样品的边缘位置,晶界面趋向于{110}与{112} 取向,且其数量高出随机晶界28%。更具体地,小角和大角晶界中均呈现这种晶界面的各向异性分布。

英文摘要:
??????The hot-rolled textures in a 5083 aluminum alloy were measured by electron backscattered diffraction technique, and the results show that rolling texture components are developed unequally at different locations, moreover, grain boundary planes are also textured. Grain boundary planes favor the {111} orientation at the center of the specimen, and their population is 50% higher than the random distribution case, whereas grain boundary planes favor the {110} and {112} orientations on the surface of the specimen, and their population is 28% higher than the random distribution case. Moreover, this anisotropic distribution of grain boundary planes occurs at both low and high angle boundaries.
