Description
Summary:A critical examination of the surface mobility mechanism of stress-corrosion cracking of Galvele is presented. Using arguments based upon the thermodynamics of stressed solids serious errors in the development are elucidated and an accurate analysis of his ideas is presented. It is shown that the original treatment of surface mobility overestimates stress-corrosion crack velocities in ductile fee metals by about 14 orders of magnitude.
