Effect of Carbon Content on Microstructure and Mechanical Properties of WC-10Co Cemented Carbides AITranslate
Abstract AITranslate
In order to clarify carbon content range of cemented carbides with the best microstructure and mechanical properties,WC-10 Co composite powders with different carbon contents were prepared,and the cemented carbides were obtained by pressing and sintering.The effects of carbon content on microstructure and mechanical properties of the cemented carbides were analyzed by metallographic microscope,scanning electron microscope,hardness tester and electronic universal mechanical testing machine.The result show that there is decarburized phase in the cemented carbides with less carbon content than 5.34%,and carburized phase appears in the cemented carbides with greater carbon content than 5.50%.When the carbon content is 5.36%~5.47%,the cemented carbides are in the WC+Co two-phase region.When the carbon content is lower than 5.38%,WC grains present a nearly elliptical shape.When the carbon content is increased to 5.41%,the edges of WC grains tend to be flat and straight,and as the carbon content continues to increase,the growth of WC grains is more obvious,until they develop into the balanced morphology of triangular prism shape.When the carbon content ranges from 5.41%to 5.47%,the cemented carbides have better hardness and flexural strength than those with other carbon contents,and their hardness and flexural strength are 1655~1668 kg/mm2 and 3921~4475 MPa,respectively.
