Tritium diffusive transport parameters and trapping effects in the reduced activating martensitic steel optifer-Ivb
A time-dependent gas-phase isovolumetric desorption technique has been used to obtain the hydrogen isotopes transport parameters for the range of temperatures from 423 to 892 K and driving pressures ranging from 4E4 to 1E5 Pa. For protium and deuterium the properties diffusivity (D), Sieverts' constant (Ks), permeability (Phi), trapping energy (Et) and trap sites concentration (Nt) are given. The dynamics of the hydrogen isotopes transport and the origin of the trapping phenomenon are discussed in connection with the OPTIFER-IVb microstructure.
