On the Dissolution of WC in WC-Co Alloys


Article Preview

Transitional metals, such as V, Nb, Mo and Ti, were used to control the growth of ultrafine WC particles. Based on a study of the microstructures these metals were effective in inhibiting the growth of WC. The interaction parameter measured between those metals and W in a Co melt was a positive quantity. This indicates that the presence of V, Nb, Mo or Ti would tend to reduce the solubility of W in a Co melt, thus inhibiting the dissolution and growth of WC.
