Abstract
The mechanical properties of WC/Co cemented carbide with WC grain size of up to 30 μm are investigated through compressive and transverse rupture tests, because it is now to produce WC/Co cemented carbide of which grain sizes are from 20 to 30 μm. From testing specimens with a WC grain size of 3-30 μm and Co content of 5-20 wt.%, it is found that WC/Co cemented carbide with larger WC grains (20-30 μm) exhibit ductility, whereas smaller-grained materials are characteristically brittle.
