“…The same powder was used for manufacturing M2 reference samples. The TiCN powder was selected with the molar composition 0.5C-0.5N, that has been reported to be the most beneficial for hardness, bending strength (Zhang et al, 2006) and oxidation resistance (Pastor, 1988). The characteristics of starting powders are given in Table 1.…”

This work is focused on the cutting performance of a new cermet based on high-speed steel (HSS) matrix with hard phase TiCN. The processing route to manufacture the cermet M2 + 50 vol.% TiCN is described. Orthogonal cutting tests, carried out in a lathe showed the ability of the new cermet to achieve turning operations, showing reasonably wear resistance performing dry cutting operations. Tool life was significantly increased, when the cermet was compared with the reference material M2 without reinforcement and with commercial HSS M2. Evolution of flank wear and chipping wear, being the dominant wear patterns, were analysed.

“…The density of the sintered samples was determined according to Archimedes' law and their microstructures were observed by SEM. For comparison, a sample containing identical chemical components was also sintered at 1400°C for 2 h in vacuum, as prepared previously [12].…”

Ultra-fine titanium carbonitride (TiCN) matrix materials with a grain size less than 1 μm were successfully prepared by vacuum microwave sintering. The milling process for raw TiCN particles and the microstructure and properties of cermets produced with a composition of 15wt.%WC-17wt.%(Co+Ni)-9wt.%Mo 2 C-59wt.%Ti 0.7 N 0.3 and sintered by vacuum microwave were analyzed by scanning electron microscopy (SEM) and X-ray diffraction (XRD). The results show that a ball-to-powder mass ratio of 8:1 and a milling time of 50 h provided appropriate conditions for the production of ultra-fine TiCN solid solution powders. The use of vacuum microwave sintering produced cermets with much finer grain and black core structures and higher relative density and hardness than those produced by vacuum sintering technology.

“…The mechanical properties of TiC(N)-based cermets have been improved by adding various elements. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] Mo is one of the main additive elements for cermets. It enhances the wettability of hard phase with binder phase and refines crystal grain of the hard phase, and thereby improves fracture toughness of the compact.…”

“…[6][7][8] Other carbides are added to modify the physical and mechanical properties of the cermet according to use conditions. [11][12][13][14][15][16][17] The additive elements for cermets cause the hard phase of the TiC(N)-based cermets to become corerim structures consisting of a TiC(N) core and a (Ti,X,Y)C rim (X and Y denote the additive elements). It is well known that microstructural inhomogeneity leads to deterioration of the mechanical properties of the cermet.…”

Microstructures and Mechanical Properties of (Ti<SUB>0.8</SUB>Mo<SUB>0.2</SUB>)C-30 mass% Ni without Core-Rim Structure

Mechanically alloyed powders having the composition (Ti 0:8 Mo 0:2 )C-30 mass% Ni were sintered at 1723 K for 2, 3, and 6 h. After sintering, a TiC phase without a core-rim structure and a Ni phase appeared. In addition, the X-ray diffraction spectrum of 6 h sintered compact showed a Mo peak. With an increase in the sintering time, the hard phase grain size, mean free path of the binder phase, and the binder phase volume fraction increased. The transverse rupture strength and Vickers hardness of the sintered compacts were measured. The maximum average transverse rupture strength was 1.51 GPa for 3-h sintered compact. The relationship between the hardness and the microstructure could be explained by the composite law including the structural factors. 2-h sintered compact had the highest hardness because of the relatively short mean free path of binder phase. 6-h sintered compact had the largest grain size, lowest volume fraction of the hard phase, and the longest mean free path of binder phase. However, this compact was harder than 3-h sintered compact because of the significantly high hard phase contiguity.
