Advances in Materials Science and Engineering, Volume 2023, Issue 1, 2023., 2023 Heat‐treated steel is widely used in industrial applications due to its high strength and other desirable mechanical qualities. Grinding, which requires a lot of power and is expensive, is typically used to harden machining. In recent times, hard machining has emerged as a viable alternative to grind in select applications.

Evaluation of machining performance of STAVAX with PCBN tools [PDF]
The International Journal of Advanced Manufacturing Technology, 2004 A study was undertaken to investigate the wear characteristics of polycrystalline cubic boron nitride (PCBN) cutting tools and surface integrity during machining of STAVAX (specialised stainless steel) with and without coolant. Plastic deformation and formation of overtempered martensite and white layer (untempered martensite) were the dominant ...

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 ...

Physico-chemical features of tool wear of PCBN
International Scientific and Technical conference "The Progressive Technics, Technology and Engineering Education", 2023 The effects of physical and chemical interaction between a tool equipped with a superhard composite based on cubic boron nitride (SBNB) and the components of the material being processed and air oxygen were studied using the results of the study of model thermal activation and real thermal triboactivation of the tool contact areas in the cutting zone ...

The Journal of Pathology: Clinical Research, Volume 8, Issue 5, Page 481-491, September 2022., 2022 Abstract Current biomarkers are inadequate prognostic predictors in localized prostate cancer making treatment decision‐making challenging. Previously, we observed that the combination of more variable telomere length among prostate cancer cells and shorter telomere length in prostate cancer‐associated stromal cells – the telomere biomarker – is ...
