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.

Application of Polycrystalline Cubic Boron Nitride for Cutting Tools.

THE REVIEW OF HIGH PRESSURE SCIENCE AND TECHNOLOGY, 1994
Polycrystalline cubic boron nitride (pcBN) materials, which are produced by sintering cBN powder and binder material under ultra-high pressure and temperature conditions, have so high hardness, high thermal conductivity and very weak affinity for ferrous metals that pcBN has been used for cutting ferrous metals such as hardened steel, cast iron, powder

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, Volume 38, Issue 43, 3 August 2026.
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.
