The influence of hydrogen on plasticity in pure iron-theory and experiment
Peng Gong, Ivaylo H. Katzarov, Anthony T. Paxton +1
Tensile stress relaxation is combined with transmission electron microscopy to reveal dramatic changes in dislocation structure and sub structure in pure alpha iron as a result of…
The influence of hydrogen core force shielding on dislocation junctions in iron
Haiyang Yu, Ivaylo H. Katzarov, Anthony T. Paxton +2
The influence of hydrogen on dislocation junctions was analysed by incorporating a hydrogen dependent core force into nodal based discrete dislocation dynamics. Hydrogen reduces th…
Quantum rate theory of the trapping of hydrogen and deuterium by a vacancy in iron
Ivaylo H. Katzarov, Anthony T. Paxton
We apply quantum rate theory to calculate the transition rates as hydrogen or deuterium atoms escape from a vacancy trap in iron into a neighbouring metastable site. We determine t…
Is the pinning of ordinary dislocations in gamma-TiAl intrinsic or extrinsic in nature? A combined atomistic and kinetic Monte Carlo approach
Ivaylo H. Katzarov, Anthony T. Paxton
We address the question of the observed pinning of 1/2 <110] ordinary screw dislocations in gamma-TiAl which leads to the characteristic trailing of dipoles in the microstructure.…
