Novel binder for NbC-based cemented carbides prepared by spark plasma sintering

The most advanced alternative to replace cobalt in cemented carbides is alloys based on the Fe-Ni-Co system due to their similar or superior properties to conventional Co-binder. However, recently, successful cermet alloys with Fe-Ni-Nb as a binder have been reported. In this work, cemented carbides...
