Notes:
The SPS process is a synthetic technique which enables sinter-bonding to occur at lowtemperature and within a short sintering time. Furthermore, it produces finer grain size thanconventional sintering methods. Fe-TiC system is a relatively light material and is one third the sizeof tungsten carbide and less than half weight of tool steel. It is cost effective when used in Fe-TiCsystem due to high mass effect with low density and relatively low cost of changing tools andbearings. Fe-TiC system can be machined easily with conventional equipment. In the present work,SPS was conducted at the temperatures of 1200, 1250 and 1300℃ at the sintering time of 3, 5 and10min. As the sintering temperature and holding time increased, the relative density decreased andthe hardness reached the lowest at 1250℃. These are attributed to the more pore being generated byliquid Pool at 1250℃ and 1300℃. The result of the microstracture observation showed more M6Cand MC carbide by liquid Pool as sintering temperature and holding time increased
