Fracture Properties of PCBN as a Function of Loading Rate and Temperature [PDF]

open access: yesKey Engineering Materials, 2010
Polycrystalline Cubic Boron Nitride (PCBN) is a super-hard material used in some of the most demanding material removal operations today. These include turning of hardened steels, as well as the machining of highly abrasive alloys. In these applications the tools are subjected to high operating temperatures, abrasive and impact loading.
