Formation of TiC-Reinforced Iron Based Composite through Carbothermal Reduction of Hematite and Anatase

Abstract:

Article Preview

In this research carbothermal reduction of mechanical activated hematite (Fe2O3), anatase (TiO2) and graphite (C) mixture was investigated. Mixture of raw materials with composition of Fe-20vol%TiC was mechanically activated in a planetary ball mill with different milling time (0h-60h) in argon atmosphere. X-ray diffraction (XRD) results showed the intensity of Fe2O3 reduced with milling time. The activated powders were pressed using cold pressing under a constant pressure (100MPa) and heat treated at 1100°C for sintering in a vacuum furnace. The increase in milling time resulted in the formation of iron (Fe) and titanium carbide (TiC) phase as confirmed by XRD result.
