“…electrolytic permeability measurement (Fiore and Kargol gen in annealed or cold-worked specimens. This 1981, Mezzanotte et al 1980). In the temperature range observation is unusual in that trapping of hydrogen 3t of 17 to 90°C, hydrogen diffusivity was measured in micro-or submicrostructural features, e.g., dislocations, annealed, annealed plus aged, cold-worked, is usually expected in metals or alloys.…”
