In this work, the effects of micron grained WC additions on the microstructure and properties of ultrafine WC-(micron WC-Co) cemented carbides produced through low pressure sintering processes were investigated by scanning electron microscope and mechanical properties tests. The results show that the obvious crack deflection and transgranular fracture phenomenon could be observed with the addition of micron WC, which can resist the crack propagation and improve the toughness of cemented carbides. The sintered ultrafine WC-(micron WC-Co) hardmetals demonstrate excellent hardness and fracture toughness values (HV30: 1700 kg/mm(2), KIC: 13.82 MPa m(1/2)). These inhomogeneous ultrafine WC( micron WC-Co) cemented carbides have considerable potential for use in structural applications. (C) 2014 Elsevier B.V. All rights reserved.
