Abstract

The formation of a sub-micron sized powder composed of nanocrystalline alumina and titanium carbonitride of two different stoichiometries during highenergy ball milling is reported in this paper. The starting materials wererutile (TiO2), graphite and aluminium powder. A similar composite with iron was also produced using the mineral ilmenite (FeTiO3) as the starting material. The powders were ball milled together under a nitrogen atmosphere for 100 h in a laboratory scale mill and subjected to thermal analysis and isothermal annealing at up to 1200 degrees C. X-ray diffraction showed that the phases were formed during the milling step and underwent grain growth and then reaction upon annealing. Differential thermal analysis indicated no residual elemental aluminium after milling confirming that the reaction wascomplete within the mill. (C) 1999 Acta Metallurgica Inc.
