, 2018 Polycrystalline cubic boron nitride (PcBN) is a super-hard material with a multiphase composite character. As it is the case for other super hard materials, information on the smallscale response of PcBN is rather scarce. In this sense, the present work conducts a systematic micro-mechanical study of the mechanical integrity of a cBN embedded in ...

Tool Wear Inspection of Polycrystalline Cubic Boron Nitride Inserts [PDF]
In industry, highly frequent inspection of tooling used to machine safety critical components is common place. Worn or damaged tools produce undesirable surface finishes leading often to early failure of the part due to fatigue crack growth. In the development stages of polycrystalline boron nitride tools, the tool wear inspection technique is an off ...

Synthesis and Characterization of Polycrystalline Cubic Boron Nitride Composites with Al Binder [PDF]
Advances in Engineering Research, 2015 The PcBN materials were sintered from the cBN-Al systems under high-pressure and high-temperature, and the mechanical properties, composition and microstructure of prepared samples were analyzed. The results show that the microstructure is fairly even and the binding phase is uniformly distributed in its volume.

Polymorph‐Specific Electronic Transduction in WO3 during Molecular Sensing
Advanced Materials, EarlyView.Metal‐oxide polymorphs with similar surface chemistry can nevertheless exhibit distinct sensing properties. In γ‐ and ε‐WO3, analyte adsorption appears comparable; yet, only ε‐WO3 induces a pronounced lattice electronic perturbation that accommodates charge in sub‐conduction band minimum states.
