Research status and development trend of new nanocrystalline cemented carbides

Nanocrystalline cemented carbides have been widely used in the electronics information, automobile manufacturing, aerospace, national defense, and military industry due to the excellent performance. The development of nanocrystalline cemented carbides in recent years was summarized in this paper, including new binder phase nanocrystalline cemented carbides, binderless nanocrystalline cemented carbide, gradient nanocrystalline cemented carbides, and coating nanocrystalline cemented carbides. The development potential and research focus of the nanocrystalline cemented carbides in each field were prospected, providing the new ideas for the modern cemented carbide materials and technology.
