Thermo-radiative and optical properties of a cutting tool based on polycrystalline cubic boron nitride (PCBN) [PDF]
Materials Research Express, 2016 The normal spectral emissivity of a cutting tool based on polycrystalline cubic boron nitride (PCBN) between 400 °C and 1000 °C has been measured. Its shape shows significant differences with respect to that of pure cubic boron nitride (c-BN). Therefore, while the reflectance spectrum of pure c-BN can be fitted to a Lorentz model for linear dielectrics,

, 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 ...

The effect of hydrogen on the fracture toughness of friction‐stir welded API 5L X70 pipeline steels
Fatigue &Fracture of Engineering Materials &Structures, Volume 45, Issue 10, Page 3009-3024, October 2022., 2022 Abstract The hydrogen embrittlement (HE) leads to severe steel degradation of mechanical properties. The hydrogen atoms diffuse into the steel and get positioned into reversible and irreversible trap sites. The pipe to transport oil and gas needs to be welded to construct long‐distance pipeline projects; thus, friction‐stir welding (FSW) has proven an ...
