Abstract
The attenuation of Rayleigh surface acoustic waves was measured for various stainless alloys during and after electrolytic charging with H. The change in attenuation is related to the cathodic current density, type of alloy, and its state. The H-egress measurements indicate that the H-pinning of dislocations is a major source of attenuation change. The data follow the Granato-Hikata-Lücke model and display (time)1/2 kinetics, consistent with that expected for dislocation unpinning.
