Abstract:The mechanical properties and microstructure of Ti(C, N) based cermets have been studied. The experimental results have shown that the cermets investigated are of good mechanical properties, and their microstructures consist of ceramics and metals. The ceramics in cermets are divided into two types depending on their diameter sizes. Small particle ceramics with diameter less than 0.7μm is the single ceramics (Ti, W, Mo)(C, N), and the large one with diameter greater than 1μm consists of core and rim, in which case the core is pure TiC and the rim is (Ti, W, Mo)(C, N). This work suggests that the core and rim have the same crystal structure, lattice parameter and orientation. An orientation relationship between the ceramics and metals has also been found.
