Wear-adaptive optimization of in-process conditioning parameters during face plunge grinding of PcBN

Scientific Reports, 2022
Polycrystalline cubic boron nitride is a very hard material. Machining of this material is performed by grinding with diamond tools. Due to its high hardness, grinding tools are subjected to severe microscopic and macroscopic tool wear.

Toward the Application of Multiaxial Failure Criteria: Mean Stress Sensitivity of Carbide‐Rich, High‐Alloy PM‐HIP Tool Steels Under Axial and Torsional Cyclic Loading

steel research international, EarlyView.
This study quantifies axial and torsional long‐life fatigue (LLF) behavior of three carbide‐rich PM‐HIP tool steels, correlating LLF strength with intrinsic defect size and cleanliness, thereby extracting material‐specific mean stress sensitivities and Haigh diagrams.

Reaction sintering of polycrystalline cubic boron nitride at high pressure and temperature.

Journal of the Japan Society of Powder and Powder Metallurgy, 1989
Single phase sintered compact of cBN (polycrystalline cBN) may be prepared under high pressure and temperature (>5.2GPa, >1350°C) from hBN compact carrying a small amount of Mg3BN3 as a catalyst. This work investigated the influence of the amount of Mg3BN3 added to the hBN compact on the microstructure and the thermal conductivity of the prepared ...

High‐Pressure Synthesis and Chemical Bonding of Mg3BiN

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 10, 7 July 2026.
The anti‐perovskite Mg3BiN is obtained by high‐pressure high‐temperature reaction of Mg–Bi mixture with boron nitride serving as crucible material. The compound is electron precise with essentially ionic bonding, and DOS calculations indicate semiconducting behavior.

Thin Fluoride Insulators for Improved 2D Transistors: From Deposition Methods to Recent Applications

physica status solidi (RRL) – Rapid Research Letters, Volume 20, Issue 7, July 2026.
2D materials hold significant promise for next‐generation electronic and optoelectronic devices, but suitable gate dielectrics are still a challenge. Fluoride insulators, offering inert, dangling‐bond‐free surfaces, have recently emerged as strong candidates. This review covers recent publications on high‐quality fluoride thin‐film deposition and their
