摘要：

Special features of deformation and recrystallization textures in a copper capillary tube produced by drawing and subjected to annealing in a vacuum furnace at 500 degrees C for 5.5 h are studied. The textures of the specimens are analyzed by the EBSD technique. It is shown that both textures are homogeneous over the entire cross section of the tube and match on the whole the deformation and recrystallization textures of cold-rolled copper sheets. Grains with orientations located at the scattering edges of the deformation texture grow under the recrystallization and deviate from the accurate deformation orientations by turning about their axes by 50 - 70 degrees going close to . A hypothesis explaining the recrystallization texture by formation of nuclei in the regions of deformation twins is suggested.
