摘要：

Crystallographic macrotexture of pure niobium cold rolled to 30, 60, 80 and 90% reduction was analyzed by X-ray diffraction and compared with low carbon steel texture. Annealed samples from 800 degrees C, to 1200 degrees C were investigated by X-ray diffraction and electron back scattering diffraction (EBSD). The texture of cold rolled polycrystalline niobium is characterized by a component {001} < 110 > that increases in intensity with the cold work percentage. After annealing, the component {001} < 110 > spreads out about 20 degrees.
