A mixture of ilmenite (FeTiO 3 ) and activated carbon was ball milled at room temperature for 400 h. The milled ilmenite was readily reduced to rutile during a subsequent low temperature annealing process (760°C/30 min). Thermogravimetric and X-ray analyses showed that the ball milling treatment gives rise to a lower temperature and higher reaction rate for the carbothermic reduction of ilmenite...
Fe 3 N, γ -Fe 4 N and a supersaturated solid solution of N in Fe have been formed by ball milling of pure iron powder in a nitriding atmosphere. The structural development was monitored by X-ray diffractometry and the chemical composition of the end milling product was determined using Rutherford backscattering spectroscopy. The influence of milling temperature and atmosphere on nitriding...
