Cube textured copper tapes have been prepared as possible substrates for de
position of high critical current density YBCO films with intermediate meta
llic or ceramic biaxially textured buffer layers. The cube texture was prom
oted by recrystallization after cold rolling. The deformation degree, the e
ffect of deformation reduction at each pass and the influence of annealing
temperature on the recrystallization process has been studied. Different pa
rameters have been optimized in order to obtain the sharpest cube texture {
100}[001]. The full width half-maximum mean values (FWHM) of the grains out
-of-plane measured from rocking curves in the parallel and perpendicular di
rections to the rolling are 10 degrees and 14 degrees, respectively, while
the in-plane FWHM obtained from the pole figures is 10 degrees.
