Investigation of the physical properties and structure of TiC-WC-Co alloys

1. Data have been obtained on the effect of cobalt content and heat treatment conditions on the electrical resistivity of TiC-WC-Co alloys. 2. X-ray diffraction investigations have shown that the carbide phase in WC-Co alloys is subjected to compressive stresses, while the titanium phase in TiC-WC-Co alloys in the presence of structurally-free tungsten carbide is subjected to tensile stresses. 3. Curves of bending strength and Vickers hardness vs cobalt content have been plotted for WC-Co and TiC-WC-Co alloys.
