High temperature mechanical behaviour of Ti(C,N)-Mo-Co cermets

Combustion synthesis of Ti(C, N)–TiB2 from a Ti–C–BN system

“…Ti + 0.5C → TiC 0.5 (4) TiC 0.5 + 0.25N 2 → TiC 0.5 N 0.5 (5) The discrepancy in the reaction mechanism could be due to the difference in the nitrogen source as well as the coarse C particles used in the experiments. With regard to the influence of the particle sizes of C and BN, it should be mentioned here that the reaction mechanism deduced in this work only applied to the Ti-C-BN system, with the coarse C and fine BN particles in the reactants.…”

“…Because of its outstanding physical properties, such as high hardness, high corrosion resistance and high thermodynamic stability, Ti(C, N) has been successfully used in cutting tools and wear-resistance materials when combined with metal binders, such as Ni, Co and Mo [2][3][4][5]. Furthermore, the addition of different ceramic phases (e.g., WC, Mo 2 C, TiN and TiC) into Ti(C, N) matrix could effectively improve the physical and mechanical properties of cermets to meet the requirement of the cutting task [3,[6][7][8].…”

WC–TiC–Ni cemented carbide with enhanced properties

“…According to Hall-Petch relation, hardness and transverse rupture strength of the cemented carbides will be enhanced due to the decrease of grain size. Another mechanism for the increase of mechanical properties is that the improvement of wettability between TiC and Ni due to the addition of Mo 2 C [21,22]. It is reported that TiC may be surrounded by a (Ti, Mo)C rim during sintering, hence the growth of carbide can be inhibited and the wetability is improved [23].…”

Microstructural changes during wear by plastic deformation of cemented carbide and cermet cutting inserts

“…Many studies on the deformation behavior of cemented carbides and cermets have been performed in different temperature ranges and with different deformation methods such as mechanical spectroscopy [3][4][5][6][7][8][9][10][11][12] and bending or compression testing. [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29] In addition, some studies have focused on model materials or individual phases of the material.…”
