Effect of trapping on hydrogen permeation in copper

PDF Version Also Available for Download.

Description

From international conference on hydrogen embrittlement effect on metal properties selection and design; Champion; Pennsylvania, USA (23 Sep 1973). Results of permeation experiments with high-purity copper in a deuterium atmosphere suggest that reversible trapping of deuterium occurs. Deuterium permeation was measured at temperatures between 270 and 450 deg C. A mathematical model, based on the general diffusion-plus-trapping model of McNabb and Foster, was developed to predict trap densities. Solutions were obtained for a plane sheet by the finite-difference method and are convergent and stable over a relatively wide range of parameters. Experimental results agree qualitatively with predictions of the model. ... continued below
