Figure 16. Development of ultrafine WC-Co-based cemented carbides according to the thermodynamically calculated (A) phase diagram and (B) mole percent of (Ta,W)C cubic phase in the WC-10Co-0.5Ta cemented carbides (at 1410 °C). Three dashed lines indicate the carbon contents of the samples synthesized. L = liquid, η = M6C, γ = Co binder, δ = cubic phase and C = graphite phase.
