Effects of Fe-TiB2 Addition as Binder Phase on the Liquid Phase Sintering Behaviour of Tungsten Carbide Cermets

摘要

The sintering behaviour of tungsten carbide compacts with a eutectic Fe-TiB2 mixture was studied. In order to have a clear view of the mechanisms that occur during liquid phase sintering, the hardness, transverse rupture strength, toughness, and densification values were measured and the micrographs were examined for WC-Fe-TiB2 cermets with varying compositions, sintering times and sintering temperatures. The findings were then with the propeerties known for WC-Fe and WC-Co cermets.
