INFLUENCE OF TRAPS ON THE DEUTERIUM BEHAVIOUR IN THE LOW ACTIVATION MARTENSITIC STEELS F82H AND BATMAN

摘要

A time dependent permeation method is used to measure the permeability, diffusivity and solubility of deuterium in the low activation martensitic steels F82H and Barman. The measurements cover the temperature range from 373 to 743 K which includes the onset of deuterium trapping effects on diffusivity and solubility. The results are interpreted using a trapping model. The number of trap sites and their average energies for deuterium in F82H and Batman steels are determined. [References: 29]
