The processes of the mechanochemical reactions were investigated by X-ray diffraction analysis and differential thermal analysis. The observed mechanochemical reactions seem to occur under high-energy ball impacts and are different from the corresponding thermally activated reactions. 关键词: Ilmenite;Amorphous materials;Powder metals;Nanostructured materials;Ball milling;X ray diffraction analysis;Differential thermal analysis;Mechanical alloying;Mechanochemical reactions
