“…Therefore, this compound is formed close to BN grains and the TiC phase on top of it. This conclusion is in agreement with electron microscopy results for composite with Ti additive [9]. For the sample under exami- nation, the ternary TiC 0.7 N 0.3 , TiC 0.3 N 0.7 and Ti 3 SiC 2 compound was detected by XANES but we did not have possibility to measure this compound spectrum by XPS.…”

“…Thermodynamic calculations indicate that in composites based on the c-BN the formation of bonding TiB 2 phase is most probable [8]. The existence of this phase seems to be essential for good mechanical properties of the material [9]. Therefore, it is important to find the optimal thermal and pressure conditions for this phase formation.…”

“…A fraction of phases, in particular those formed during the high pressure and high temperature sintering process, have commonly very small grains and call for high resolution techniques. Many studies have been performed to investigate how related elements and materials sinter together and which phases that form [6][7][8][9][10][11][12]. However, the morphology and position of these presumably nano-sized phases, as well as the mechanisms behind their formation are not known.…”

“…), titanium based alloys, and nickel-based super-alloys [3][4][5][6][7]. In general, PcBN is fabricated by high temperature high pressure (HTHP) sintering process using cBN powder and binders composed of ceramic materials such as TiC, TiN, TiCN, and TiB 2 [8][9][10]. Due to the high melting point of the ceramic binders, the sintering mechanism of low grade PcBN tools is mainly the solid state type, involving a reaction of cBN with the binder to form intermetallic compounds at the cBN-binder interface.…”
