In this manuscript, we investigate the influence of hydrogen on the environmentally assisted cracking of the high-strength magnesium alloy AZ31B.
Hydrogen Embrittlement of Magnesium and Magnesium Alloys: A Review – Publication
In this article, we present and debate the various hydrogen embrittlement and stress corrosion cracking mechanisms of magnesium and magnesium alloys.
Pre-exposure embrittlement and stress corrosion cracking of magnesium alloys in chloride solutions — Presentation
Do magnesium alloys suffer environmentally assisted cracking?
In this work, presented at CORROSION 2014, we investigated the hydrogen embrittlement and stress corrosion cracking of magnesium alloy AZ31B in chloride solutions.
Hydrogen diffusion control during stress corrosion cracking of magnesium alloy AZ31B in chloride solutions – Abstract
SCC of AZ31B alloy was studied in NaCl solutions at different potentials and chloride concentrations using the slow strain rate technique. A combination of pre-exposure tests followed by immediate straining or straining after a dry air exposure delay helped to weight the relative importance of anodic damage accumulation versus increased hydrogen charging during open-circuit potential pre-exposure. The dependence of ductility with pre-exposure time and the fracture surface of embrittled samples suggest that hydrogen embrittlement of AZ31B was controlled by hydrogen diffusion.
