Abstract Permeability experiments were used to study hydrogen diffusion and trapping in dual phase (DP), quenched and partitioned (Q&P), advanced high strength steels. The measured reversible hydrogen trap densities indicated that (i) trapping was less significant at a more negative potential, and (ii) the lattice diffusion coefficient of hydrogen could be measured from the partial transients at the most negative potentials. The densities of reversible hydrogen traps evaluated from complete decays from −1.700 V were ∼ 2 × 10 sites cm, and were a factor of two higher than those from partial decay transients between −1.700 V and −1.100 V.

Permeability experiments were used to study hydrogen diffusion and trapping in dual phase (DP), quenched and partitioned (Q&P), advanced high strength steels. The measured reversible hydrogen trap densities indicated that (i) trapping was less significant at a more negative potential, and (ii) the lattice diffusion coefficient of hydrogen could be measured from the partial transients at the most negative potentials. The densities of reversible hydrogen traps evaluated from complete decays from −1.700VHg/HgO were ∼ 2 × 1018 sites cm−3, and were a factor of two higher than those from partial decay transients between −1.700 VHg/HgO and −1.100 VHg/HgO.
