Titanium carbide is used as an attractive reinforcement to produce particulate metal matrix composites. One of the problems to use this carbide as a reinforcement in copper-based composites is the lack of wetability in Cu-TiC system. This property improves as the C/Ti ratio in carbide decreases. Problems to use this carbide as a reinforcement in copper-based composites is the lack of wetabiity...

In article 2100068, S. T. Britt and P. C. Pistorius study liquid titanium-bearing iron (saturated with carbon) wets alumina crucibles. Wetting is caused by reaction between dissolved titanium alumina; it can be prevented pre-treating the crucible a flux containing calcium fluoride. By avoiding wetting, clear images of carbide formation on droplet obtained, during confocal scanning laser microsc...

Fine-grained tungsten carbide copper (WC-Cu) cemented carbide was sintered via spark plasma sintering at 1773K using a fine WC powder with a mean particle size of 0.11 mm. The mechanical properties were compared with tungsten carbide cobalt (WC-Co) cemented carbide and a binderless WC-sintered material. The Vickers hardness and fracture toughness obtained by the indentation fracture method for ...
