Medium grain size tungsten carbide powder can be prepared by a high-temperature reduction-carbonization process, and the grain development is complete, the crystal lattice defects are small, the carbonization is complete, and the size is uniform. Application The average grain size of YG20C alloy produced by high temperature carbonization of medium grain size tungsten carbide powder reaches 2.4 μm or more. The properties of alloy are comparable to those of YG20C produced by high temperature reduction high temperature carbonization process. The…
