| Abstract: | The synthesis of a titanium oxynitride phase by mechanically milling elemental titanium powder in air at ambient temperature has been studied. X-ray powder diffraction, transmission electron microscopy and chemical analysis showed that milling resulted in the formation of a nanocrystalline f c c oxynitride phase having the composition TiNO0.5. The effects of milling time and subsequent heat treatment on the structure and lattice parameters are reported. The results indicate that mechanical milling significantly increases the reactivity of titanium with nitrogen. |
