Notes:
TiC-based cermets attract much attention because of their excellent wear-resistance, highhardness at high temperature, good chemical stability, superior thermal deformation resistance.Therefore, titanium carbide is mainly used for cutting tools, grinding wheels, coated cutting tips andcoated steel tools. In this research, Fe-TiC composite materials were fabricated by spark plasmasintering (SPS) after mechanical alloying. TiH2 and graphite powders were used to synthesize TiCphase. In order to compare the properties of sintered materials using mixture powder(D’AE+TiH2+graphite), commercial TiC powder was mixed with Distaloy AE (D’AE) powder as asame mechanical alloying method. Then, the shape of each mixture powder (D’AE+TiH2+graphite,D’AE+TiC (commercial)) and sintering properties were compared. TiC phase was synthesized byself-propagating high-temperature synthesis (SHS) reaction during spark plasma sintering. It wasconfirmed by using X-ray diffraction (XRD). Energy dispersive spectrometry (EDS) and Scanningelectron microscopy (SEM) were used to observe shape of mixture powders and also sinteringproperties were examined such as hardness, relative density. In case of sintered material for 10minholding time at 1373K after mechanical alloying for 1 hour with D’AE, TiH2 and graphite, it indicatedhigher hardness value 49HR-C than a case using D’AE and TiC powder
