Picosecond laser processing of polycrystalline cubic boron nitride — A method to examine the ablation behavior of a high cubic boron nitride content grade material

Journal of Laser Applications, 2015
Chipping of hardened steel is often performed by the use of polycrystalline cubic boron nitride (PCBN). Moreover, PCBN tools are also suitable for many machining tasks with a lower degree of specialization, due to their excellent mechanical properties.

Thermal Conductivity of Polycrystalline Cubic Boron Nitride Compacts

1979
Slack [1] predicts a room temperature thermal conductivity of about 13 W/cm°C for single-crystal cubic boron nitride with only diamond having a higher conductivity among the high thermal conductivity adamantine Compounds. However, no crystals of cubic BN were available that were large enough to measure the thermal conductivity, and the highest value ...

Structurization of single-phase polycrystalline materials based on cubic boron nitride

Soviet Powder Metallurgy and Metal Ceramics, 1987
The authors study the crystallization of cubic boron nitrides by means of transmission electron microscopy and electron diffraction and the effects on crystal structure and microstructure of sintering, compacting, and heat treatment. Their results establish that the structurization of the nitrides is determined by structural phase transformations ...

Shock compressibility and spallation strength of cubic modification of polycrystalline boron nitride

High Temperature, 2009
Methods of shock-wave physics are used to perform experimental investigations of the elastoplastic and strength properties of cubic modification of polycrystalline boron nitride. The samples are prepared by pressing to a pressure of 7–8 GPa at a temperature of 1700–1800 °C and rank just a little below diamond in hardness. The measurements are performed

Mechanism study on the wear of polycrystalline cubic boron nitride cutting tools

SPIE Proceedings, 2010
The samples of bearing steel, alloy cold-die steel, cold-harden cast iron were continuous machined by polycrystalline cubic boron nitride(PcBN) cutting tools dry turning. After the machining, the phases of cutting tools blade-edge were analyzed by X-ray diffraction analyzer and cutting tools blade-edge microstructure were observed by scanning ...
