The application backgrounds of cemented carbide with novel binders are introduced. The characteristics and latest progress of cemented carbide with Ni-based, Fe-based, composite metal-based and intermetallic binder phase are summarized. The various mechanisms of the binder phase strengthening, such as precipitation, second phase particles and solid solution strengthening, are discussed. The new techniques used in the research of novel binders are introduced.Especially, the application of phase diagram calculation tools and the EBSD detection technology accelerates the research and development of novel binders. The problems in the research and development of cemented carbide with novel binders are pointed out. These key researches should be focus on the fundamental theory, detection method and preparation technology of novel binder materials in the future.
