Measurement of the saturated dislocation pinning force in hydrogenated nickel and nickel base alloys

Measurement of the saturated dislocation pinning force in hydrogenated nickel and nickel base alloys

Static strain ageing experiments are used to measure the saturated dislocation pinning force as a function of the hydrogen concentration in hydrogenated nickel and binary nickel—16 wt% chromium. The role of hydrogen transport by mobile dislocations on hydrogen embrittlement is demonstrated.
