cBN–TiN, cBN–TiC composites: chemical equilibria, microstructure and hardness mechanical investigations

Densification and microstructure of Al2O3-cBN composites prepared by spark plasma sintering

“…We as well as other researchers have reported that TiN and TiC significantly reached with cBN to form TiB2. 21),22) AlN, AlB2 and α-AlB12 were also formed in Al-cBN composites at 1200 to 1400°C.…”

Nanostructure of a cubic BN cutting tool material

“…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.…”

Characterization of the c-BN/TiC, Ti3SiC2 systems by element selective spectroscopy

“…It is a reason of increasing interest concerning materials with extreme hardness, corrosion resistance, and suitable thermal and electrical properties. Composites based on the cubic boron nitride (c-BN) have recently attracted increasing attention due to the possibility of the synthesis of materials with unique properties such as super-hardness, combined high hardness and low friction, high corrosion resistance, attractive thermal and electrical properties [1][2][3][4][5][6]. Cubic boron nitride, with its diamond structure, is thermodynamically stable under high pressure and temperature.…”
