Polycrystalline γ-boron: As hard as polycrystalline cubic boron nitride [PDF]
Scripta Materialia, 2012 The Vickers hardness of polycrystalline γ-B was measured using a diamond indentation method. The elastic properties of polycrystalline γ-B (B=213.9 GPa, G=227.2 GPa, and E=503.3 GPa) were determined using ultrasonic measurement at ambient condition. Under the loading force up to 20 N, our test gave an average Vickers hardness in the asymptotic-hardness

The influence of microstructure on the fracture statistics of polycrystalline diamond and polycrystalline cubic boron nitride [PDF]
Ceramics International, 2014 Abstract Flexural strength data of a number of grades of polycrystalline diamond (PCD), and polycrystalline cubic boron nitride (PCBN) were analyzed using Weibull, normal and lognormal distributions. The role of microstructure in the failure mechanism of such materials was analyzed in terms of the chosen strength distributions.

Pulsed laser micro ablation of polycrystalline cubic boron nitride
Procedia CIRP, 2020 Polycrystalline cubic boron nitride (PcBN) is the second hardest material after diamond. Because of its unique properties, PcBN is extensively used as a cutting tool material for the machining of hardened steels. Pulsed laser ablation (PLA) offers the possibility to generate tailored microgeometries on PcBN tools and can thereby increase tool ...
