Abstract The present work investigates the resistance of a progressively cold-drawn carbon steel wire against hydrogen embrittlement. In this study, analytical and numerical methods are used to determine critical content, ratio embrittlement indices different material conditions. with highest degree cold deformation shows content improved At higher degrees deformation, stronger trapping, which ...

Hydrogen is a dangerous gas due to its low ignition energy, wide flammability range, promotion of the embrittlement steel, and high coefficient permeation for polymers. The fracture toughness failure elongation pipe steels are strongly impacted by hydrogen embrittlement, whereas yield stress ultimate strength moderately impacted. Specific tools required defect assessment used transport hydrogen...

Recent studies have revealed that hydrogen embrittlement in Al–Zn–Mg alloys appears to be dominated by partitioning MgZn2 precipitates. A method has recently been proposed for reducing the concentration at precipitates adding specific intermetallic compound particles high trap energy. In present study, effectiveness of Al7Cu2Fe on suppression Al–Zn–Mg–Cu was evaluated using X-ray microtomograph...
