Effect of Carbon Content on Microstructure and Properties of WC-3Co-3Ni Coarse Grained Cemented Carbide AITranslate
Abstract AITranslate
In order to explore the effect of carbon content on the microstructure and properties of coarse grained cemented carbide with Co-Ni composite binder phase, the change rules of microstructure and pro-perties of WC-3 Co-3 Ni coarse grained cemented carbides with different carbon contents were studied by optical microscope, Rockwell hardness tester, coercivity tester and cobalt magnetometer.The results show that the coercive force of alloy increases with the increase of ball milling time, and reaches its maximum value when the ball milling time reaches 22 h.With the increase of carbon content, the WC grain morpho-logy is more angular, the dissolution-precipitation process makes WC grains coarser, the bending strength increases and the hardness decreases.When the milling time is prolonged, the increase of hardness caused by the decrease of carbon content is greater than that caused by the increase of carbon content.
