    Research outputpeer-review


    Interaction of hydrogen with dislocations studied by means of classical molecular dynamics simulations. Two types of interatomiic potentials were tested and vallidated by comparing with ab initio data. Strong attraction of H to screw and edge dislocation was demonstrated. Dymaic calulcations at finite temperature showed one dimentional migration of H atoms along the dislocation core.
