Abstract
In this article, the effect of sintering temperature was studied on the microstructure and hardness of cemented tungsten carbide and steel bilayer fabricated via the powder metallurgy route. Cemented tungsten carbide was reinforced with Fe and also used as the base material for the other layer to ensure compatibility between layers. Carbon addition was varied in the steel part composition to avoid carbon-deficient bilayer samples. Optical images revealed cracks at the interface which opened up more in bilayer samples sintered at 1295°C due to high mismatch in strain rate and excessive diffusion rate. Increase in sintering temperature turned grain particles coarser and lead to a decline in hardness values while increase in carbon addition enhanced densification and progressively increased hardness. Hardness values measured far away from the interface were observed higher than those close to the interface due to the formation of weak bond at the interface.
