Solubility and Diffusion of Hydrogen in Metals and Alloys. I - Monocrystalline Nickel-Vanadium Alloy

摘要

A method for measuring the solubility and diffusion coefficient of hydrogen in metal single crystals under clean conditions is described. For a nickel - 4.4 atom % vanadium alloy the diffusion coefficient is (7.2 +or- 0.4) x 0.0001 exp (-10.10 +or- 0.06 kcal/RTsq cm/sec and the solubility in atom H per atom of alloy is (1.12 +or- 0.05) x 0.0001 exp (-2.09 +or- 0.05 kcal/RT).
