as annealing time led to the formation of Cube texture component, which is a major component of recrystallized low stacking fault energy materials. Furthermore, D and Rt-Co components formed during... in the samples annealed for 5 and 30 min at 900 °C. Increasing annealing time to 60 min led to the formation of a Cube texture component and weakening of the S1 component; nevertheless, Rt-G and brass......
rotated cube texture component in place of the cube component, which generally appears to be the dominant component in rolling deformation. The occurrence of preferential growth of rotated cube grains may give rise to the strong intensity of rotated cube orientation in recrystallized texture. Key words: aluminum alloy; equal channel angular pressing; recrystallization; texture 近十几年来, 等通道角挤压(ECAP......
cube texture in the hot-rolled strip. During the process of producing Al sheets through modern high-speed hot tandem mill, full recrystallization is expected to take place during coiling of the hot-rolled strip, i.e., the so-called self annealing, so as to develop a favorable amount of the cube texture. However, the extent of the recrystallization during self-annealing is largely influenced......

了对比度调整,然后根据数字图像分割技术提取岩石中的空隙和裂隙.在此基础上,利用Marching Cube算法进行连续CT断层图像的三维重建,实现了岩石加载试验中不同阶段的裂纹分布的可视化.此方法不仅可以直观地观察到岩石的损伤演变情况,而且准确地描述了岩石材料内部介质的空间分布,同时结合损伤理论定义了以损伤体积作为损伤因子的损伤变量,得到损伤变量与偏应力间的关系曲线,合理地反映出岩石在损伤偏应力作用下的损伤演化特性.关键词:CT图像; 数字图像处理; Marching Cube算法; 三维重建; 裂纹; 岩石损伤......

in the repaired area and the consistency between the repair directions with structural content. Image repair algorithm with texture information performs well in repairing seriously damaged images, but it has bad performances when the images have the abundant structure information. The dual optimization image repair algorithm based on the linear structure and the optimal texture is proposed. The algorithm......
