Abstract: The microstructure of ultra-fine grade Ti (C,N)-based cermets was examined by X-Ray Diffractometry (XRD), Transmission Electron Microscopy (TEM) and Scanning Electron Microscopy (SEM). A kind of new core/rim structure and an unknown compound based on Ni, Mo, W and C were detected and their formation mechanisms were discussed.

Keywords: cermets; microstructure; ultra-fine powders; mechanical properties; titanium; carbon nitride; cutting tools; tool inserts; machining; machinability.
