Abstract: Computations were carried out involving the lifetime of macroscopic ball-shaped Hydrogen Concentration (HC) inhomogeneities in palladium. It was shown that hydrogen-elastic stresses slow down the solubility of HC inhomogeneities. The influence of hydrogen-elastic stresses increases considerably as inhomogeneity dimensions increase.

Keywords: metal-hydrogen systems; hydrogen diffusion; hydrogen-elastic effects; hydroelastic effect; diffusion slowing; palladium; hydrogen concentration inhomogeneities; mathematical modelling.
