Abstract
The effect of hydrogen in solid solution in nickel on the surface and grain boundary free energies at 1573 K was determined using the zero creep technique. Effects of O and H adsorption on the surface free energies were considered and shown to have only small effects under the experimental conditions. The surface energy of pure nickel was determined to be about 2.34 J/m2. H concentrations of 300 at. ppm were shown to have no significant effect on the surface energy. Hydrogen had a somewhat greater effect on the grain boundary energy with\(\gamma _{{\rm N}i}^{GB} /\gamma ^{GB} _{Ni - H} \approx 1.21\). The implications of these results for hydrogen embrittlement mechanisms in Ni are discussed.
