Abstract

A time dependent permeation method has been used to measure the transport and inventory parameters of hydrogen and deuterium in the precipitation hardened (PH) Cu-0.65 wt% Cr-0.08 wt% Zr alloy (ELBRODUR HF). The measurements cover the temperature range from 553 to 773 K using a hydrogen or deuterium pressure in the range 1-100 kPa. The permeabilities, diffusivities and Sieverts' constant values for ELBRODUR obtained in this work were about 2 time higher, 2 times lower and between 3 and 10 time higher respectively to that of Cu (F. Reiter et al., A compilation of Tritium Material Interaction Parameters in Fusion Reactor Materials, EUR 15217 EN (1993)) in the temperature range studied. Using the measured diffusivities and Sieverts' constant values for H2and D2and a quantum-mechanical model, an extrapolation for tritium is also presented. © 1998 Elsevier Science B.V.
