Abstract:

The sensitive electrochemical permeation technique was used in conjunction with scanning electron microscopy and tensile loading to determine i hydrogen diffusivity and solubility, ii effect of plastic deformation on the above parameters, and iii structural features and kinetics of hydrogen embrittlement, in Armco iron and 4340 steel.
