By selecting flexible polycrystalline Ag as the metallic substrates, highly c axis (001) textured YBCO thin films were fabricated by using a modified magnetron sputtering equipment which can accomplish dynamic deposition and in-situ anneal treatment. The textures of Ag substrates have important effects on forming YBCO films with high critical current densities. Research on the textures of cold rolling Ag at different deformation degrees and recrystallization textures of Ag at different temperatures shows that in plane alignment of YBCO films is difficult to be obtained directly on cold rolling Ag substrates, because of the texture change of Ag during deposition heating of substrates and the strong dependence of J c of YBCO films on grain boundary misorientation angle of substrates. The recrystallization textures with cube (001) and rotated cube (001) in Ag were obtained. Experiments offer a possible prospect for the further research of fabricating sharp biaxially texture in Ag and the following deposition of high J c YBCO films directly on it. 展开更多

The texture change along the normal direction to rolling plane of cross shear rolled commer- cial copper has been studied by means of two step method for ODF caleulation and computer simulation.The texture of cross shear rolling of copper is similar in primary components to that of conventional cold rolling,but the scattering degree and direction of the texture are dif- ferent,due to the residual shear strain change in different position along the normal to rolling plane.It seems that no more effect of the shear strain upon the recrystallization texture. 展开更多
