Columnar grains of β -phase were produced on single- and polycrystals of copper by the solid phase diffusion of zinc atoms, and their crystallographic features were studied by means of X-ray measurements. Special attention was paid to determine the growth direction of β -phase and to study the structure of the α/β interface. The coarse grains of β -phase were found to grow on the α -phase, in agreement with Kurdjumov-Sachs' or Nishiyama's orientation relationship. The growth direction of these grains and the associated interface structure were found to be affected by the surface orientation of the single crystals. The α/β interface was as follows:
