The longer the sample is milled, the lower the temperature of full nitridation. The enhancement of ball milling on the carbothermic reduction and nitridation reaction is due to particle size reduction, nanocrystalline structure and in particular, the intimate mixing between the milled ilmenite and graphite particles 关键词: annealing;cermets;iron alloys;mechanical alloying;nanostructured materials;particle size;powder metallurgy;reduction (chemical);thermal analysis;titanium alloys;X-ray diffraction;mechanically enhanced carbothermic synthesis;Fe-TiN composite;ilmenite-graphite mixture;low temperature annealing;ball milling;full nitridation;carbothermic reduction;nitridation reaction;particle size reduction;nanocrystalline structure;intimate mixing;milled ilmenite/graphite particles;Fe-TiN;FeO-Fe2O3-TiO2-C
