摘要：

Drastic enhancements of the interdiffusion were observed in Cu-Ni diffusion couples when samples were heated under high hydrogen pressures (similar to 5 GPa). Interdiffusion coefficients measured between 600-800 degrees C were increased by similar to 10(4) times on the Ni-rich end and by similar to 10 times on the Cu-rich end. The observation is explained in terms of superabundant vacancy formation in the presence of interstitial hydrogen atoms.
