摘要：
An electrochemical technique was used to study the effects of elastic stress on hydrogen permeation in AL 29-4-2 ferritic stainless steel. Tensile stress increased the permeability. The change in diffusivity induced by the stress was relatively inconsistent, but the activation energy consistently increased. The average partial molar volume of hydrogen deduced from the increased hydrogen flux at 40-60-degrees-C was 2.3 cm3 mol-1.
