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 ...

Polycrystalline Cubic Boron Nitride (PCBN) Tool Life and Wear in Turning of Amorphous-Crystalline Iron-Based Coatings [PDF]
Strojniški vestnik – Journal of Mechanical Engineering, 2011 The paper presents PCBN-Ciborit cutting tools life and wear test results. The effects of the machining regime when turning amorphous-crystalline Fe80B20 and Fe79Cr16B5 coating systems applied to conventional workpiece materials were assessed. It has been shown that the observed tool wear mechanisms are complex in their character and are dominated by
