heal.abstract	A macroscopic study of the growth of a stress corrosion crack in an aluminum alloy was undertaken by using the optical method of caustics. The dependence of the crack-tip stress intensity factors KI on the applied stress, as well as on the molarity of a NaCl aqueous solution was studied in detail. The calculation of these quantities was made by taking into account the thickness variation of the specimen due to the corrosive environment. A criterion of the crack growth in terms of the caustics obtained by illuminating the cracked specimen by a light beam was formulated and the corresponding values of the threshold stress intensity factor KISCC were accurately determined. Finally, the creation and the evolution of the pits developed at the vicinity of the crack tip was studied and their significance on the mechanisms of fracture of the specimens was examined. © 1977.	en
