Fabrication and performances of WC‐Co cemented carbide with a low cobalt content

WC‐Co cemented carbides with a low cobalt content (≤3 wt.%) were successfully manufactured by the powder metallurgy method. The cobalt content is lower than conventional cemented carbide (3–30 wt.%), which makes the prepared alloys possess excellent hardness. The effects of cobalt content on the den...
