The development of cold rolling texture in the intermetallic compound Ni3Al(B) has been investigated as a function of rolling reduction, using the conventional pole figure as well as the orientation distribution functions (ODF) method. The textures at low degrees of deformation have been found to be similar to the rolling texture of pure Ni cold rolled to similar levels. With increasing degree of deformation, the texture in Ni3Al(B) changes to alloy type at reductions greater than 45%. This texture is characterized by the presence of a remarkably strong rotated Goss component over and above the Brass (Bs) component. Transmission electron microscopy of thin foils of the material cold rolled by 65% and more shows evidence of twinning. X-ray diffraction analysis indicates a structural change in the material from L12 to DO22 with the progress of cold work. An attempt has been made to explain the texture development in terms of this structural transformation.
