Metal matrix composites, based on M3/2 high speed steel and reinforced with two different percentages of TiCN (2.5 and 5wt%), were manufactured following a conventional powder metallurgy route: mixing, compacting and sintering. The carbide and base material powders were dry mixed and uniaxially compacted at 700MPa. After this, vacuum sintering was carried out at different temperatures to study the sinterability of manufactured composites. Effects of sintering temperature on sintering density, dimensional change and hardness with temperature were measured, and this study was completed with a dilatometric analysis. Materials were sintered at optimum sintering temperature (1275°C), and transverse rupture strength and wear behaviour of sintered materials was examined.
