Limitations of Hydrogen Detection After 150 Years of Research on Hydrogen Embrittlement

Abstract

Hydrogen Detection

During the second industrial revolution, William H. Johnson investigated a mystery that affected the British metallurgy industry. He observed that cleaning rust from iron and steel wires with acidulated water reduced their original toughness via an embrittlement effect. Gas bubbles emerging from the wires’ cracks revealed the culprit: hydrogen. In article number 2400776, Matheus A. Tunes, Peter J. Uggowitzer, and co-workers discuss how detecting hydrogen in materials remains a challenge 150 years later.
