Abstract
The iron-carbide composites have been prepared using a simple powder metallurgy (P/M) processing route, which includes compacting and sintering of mixed powders. Sintered composites were designated to have nominal composition of Fe-5 wt. % carbides (SiC, TiC and WC). Two carbide particle sizes, -20 μm and 20-32 μm, were mixed with Fe powder. The compacted specimens were sintered at 3 different temperatures, 1100, 1150 and 1200 °C. Preliminary study revealed that stability of carbide particles under sintering conditions showed its effects on microstructures and properties of the sintered Fe-carbide composites. Microstructures and mechanical properties of sintered Fe-5 wt. % carbide composites will be presented and discussed.
