The morphology and the interface features of WC grains are examined by SEM and TEM in cemented carbides WC-8 wt% Co. Three compositions --the mixture {WC ΓΎ Co binder} and the mixtures with graphite or h --are studied after treatments at 1200 and 1450 C. The effect of the C content is observed both o
