Abstract

In the present investigation the microstructure and mechanical properties of WC-10Co, WC-8.3Ti(C,N)-12Co, WC-8.3Ti(C,N)-6Co-6Ni and WC-7Ti(C,N)-2Mo2C-6Co-6Ni cemented carbides were studied. Introduction of Ti(C,N) in WC-10Co cemented carbide imposed sintering difficulties and hot isostatic pressing was required to obtain fully dense material. The modification of the binder cobalt with nickel and molybdenum did not noticeably affect the sintered microstructure. In general the mechanical properties of Ti(C,N)-containing cemented carbides were inferior to those of WC-10Co cemented carbide.
