Abstract

Metal matrix composites based on M3/2 high speed steel and reinforced with different percentages of NbC and TaC were manufactured following a conventional powder metallurgy route: mixing, compacting and sintering. Graphite, to compensate carbon losses during sintering, and copper-phosphorous, to promote liquid phase sintering, were added to M3/2 powders to constitute the base material. Carbide and base material powders were dry mixed and uniaxially compacted at 700 MPa. After this, vacuum sintering was carried out at two temperatures: 1190 °C and 1230 °C. The mechanical properties and wear behaviour of all sintered materials were examined, and their characterisation was completed with a broad microstructural study
