| Abstract: | A Ti/TiN diffusion couple, which had been prepared by isothermal annealing of a Ti sheet in nitrogen atmosphere at 1091 °C and quenched in water, was investigated by Kossel microdiffraction. Kossel patterns were obtained from all phases present in the diffusion couple ( -Ti(N),  -Ti3N2–x,  -Ti4N3–x and  -TiN1-x)It could be shown that the Kossel technique has a superior lateral resolution (10  m) compared to commercially used X-ray microdiffraction methods, especially in the case of weak X-ray radiation. |
