Abstract:

The rolling texture and the primary and secondary recrystallization texture of copper alloy sheets were measured by X-ray diffraction and electron channeling pattern method. The specimen sheets contain 0.1 mol% additional elements such as Si, Ge, P, In and Ti.
Deformation textures were not affected by all the additional elements and showed the Cu-type texture. The recrystallization texture was found to fall into two types. In case of Si or Ge addition, which slightly raised the recrystallization temperature, the primary recrystallization texture showed a sharp cube orientation and the secondary recrystallization appeared. On the contrary, in case of P, In or Ti addition, which distinctly raised the recrystallization temperature, the primary recrystallization texture showed a weak cube orientation mixed with other orientations and no secondary recrystallization occurred.
The obtained results are discussed in relation to stacking fault energies and grain boundary structures.
