Effects of Powder Mixing Processes on Mechanical Properties of Ultrafine Cemented Carbides AITranslate
Abstract AITranslate
The effects of three original powder mixing methods including mechanical ball milling,dispersant dispersion and ultrasonic vibration on the mechanical properties of sintered WC-based cemented carbide samples were systematically studied.The results show that the density of the cemented carbide prepared by PEG dispersion is the lowest,while the density of the cemented carbide prepared by ultrasonic vibration is the highest and its mechanical properties are the best:relative density of 97.8%,Vickers hardness of 21.47 GPa,fracture toughness of 11.2 MPa·m1/2,bending strength of 1123.6 MPa and grain size of 258 nm.
