EFFECT OF HEAT TREATMENT ON THE PROPERTY AND STRUCTURE OF CEMENTED CARBIDE ANVIL

The effect of heat treatment on the various property of cemented carbide and variation of composition and structure of cobalt binder phase in the cemented carbide anvil have been studied.The results have shown that the transverse rupture strength and compressive strength of cemented carbide can be raised by heat treatment,meanwhile solid state solubility and content of face-centered cubic cobalt in the cobalt binder phase of surface layer of cemented carbide anvil can be increased.Thus the operation property of the cemented carbide anvil have been improved.
