Gaseous inhibitors: A comprehensive overview on mitigating hydrogen embrittlement in pipeline steels

Published in International Journal of Hydrogen Energy, 2024

This work reviews hydrogen embrittlement risks in pipeline steels during hydrogen transport and explores mitigation using trace inhibitor gases like oxygen and carbon monoxide. It examines surface interactions, showing inhibitors slow hydrogen adsorption but cannot stop equilibrium absorption, requiring continuous supply. The study highlights how factors such as test type, pressure, and inhibitor concentration affect mitigation effectiveness.

Fractography of Hydrogen-Charged X70 Pipeline Steels under Quasi-Static Tension

Published in EUROCORR 2023, Brussels, Belgium, 2023

This work investigates the fractography of hydrogen-charged X70 pipeline steels under quasi-static tension. It analyzes microstructure, hydrogen content, diffusivity, and fracture modes in base metals and welds. Key features such as dimples, delamination, fisheyes, and quasi-cleavage regions were characterized, providing insights into hydrogen embrittlement mechanisms in pipeline steels.

Characterization of Secondary Carbides in Low-Alloyed Martensitic Model Alloy Tool Steels

Published in Swerim AB, KTH Royal Institute of Technology, 2020

This master thesis studies tool steels with iron, carbon, molybdenum, and vanadium to understand carbide effects on hardness. Two alloys were tempered at 550C and 600C, with hardness measured and compared. Alloy A was analyzed with STEM EDS and TC Prisma simulations, showing molybdenum carbides increase strength. Hardness was higher at 550C due to reduced overaging at 600C.
