Hydrogen trapping in X70 structural pipeline steel and weldments
(Chapter; Peer reviewed, 2018)Diffusion measurements and thermal desorption measurements have been performed on a X70 pipeline steel, in as received and normalized and quenched condition, after being hydrogen charged for 200 h at 100 MPa hydrogen gas ... -
Hydrogen-assisted crack propagation in α-iron during elasto-plastic fracture toughness tests
(Journal article; Peer reviewed, 2019)Elasto-plastic fracture toughness tests of a commercially pure iron were performed in air and in hydrogen gas at two different pressures. Some unique characteristics of hydrogen-enhanced cracking were exhibited at both the ... -
Hydrogen-assisted fatigue crack growth in ferritic steels – a fractographic study
(Journal article; Peer reviewed, 2018)Fatigue crack growth (FCG) behavior of a Fe-3wt.%Si ferritic alloy under different environmental conditions using in-situ electrochemical (cathodic) hydrogen (H) charging has been investigated. Three frequencies have been ... -
