Abstract
The effects of the grain refining additions V, Cr and the level of dissolved W on the structure of the Co binder phase and the hcp/fcc were investigated in this work alongside WC grain size. V was found to be a more effective grain size suppressor in materials with a coarser starting carbide grain size while Cr was more effective for finer grain material when overall WC grain size distribution was taken into account. Grain refiners and W levels had a significant effect on WC grain morphology with V additions in high W samples having a rounded appearance. Cr additions at both high and low W concentrations had a more prismatic appearance.
