摘要

In the paper, natural ilmenite (FeTiO_3) was used as the main green material to synthesize TiC-Al_2O_3/Fe composite powder by Self-propagating High-temperature Synthesis (SHS) technology and densified TiC-Al_2O_3/Fe composites were prepared in a vacuum hot-press oven. The reaction mechanism in the synthesis process was studied through theoretical thermodynamical analysis and experiment research. The effect of different synthesis conditions on the products was discussed. The relations among synthesis conditions,sintering conditions, phases composition, microstructure and properties of composites were also studied in details. A new way to synthesize the advanced TiC-Al_2O_3/Fe composites with relatively lower cost was practiced.
