✦ Synopsis

A sensitive stressometer has been used to measure the stresses produced in carbon-steels and nickel during cathodic hydrogen charging and during the decay of stress on termination of charging. A theoretical model describing the stress kinetics has been derived and used to evaluate diffusion coefBcients from the experimental data. The effect of cd on the relative amounts of plastic and elastic strain occurring during charging of annealed mild steel is reported.

R&mmLUn

tensiometre sensible a et& utilise pour mesurer les tensions mecaniques produites sur les aciers au carbone et le nickel, pendant la charge cathodique en hydrogene et l'affaiblissement de ces tensions en fin de charge.

Un modele theorique d&rivant les tensions cinetiques a ett6 etabli et utilid pour tirer le coefficient de diffusion des don&es exp&imentales.

Des indications sont foumies, concernant l'influence de la densitd de courant sur les taux respectifs ,des tensions plastique et elastique, apparaissant au cours de la charge de l'acier doux recuit.
