Sažetak
A good many research has been performed an the stress corrosion cracking of different types of steel and alloys in various corrosive media, with the objective to clarify the mechanism and solve the problems of stress corrosion cracking, which can result in dangerous kinds of damage to structures made from such materials. It has recently been found that the steady-state elongation rate (iss), determined from corrosion elongation curves under constant load, can be directly used for life-time prediction and as a criterion for assessing the sensitivity of metals to stress corrosion cracking. For this reason corrosion elongation curves were obtained experimentally at different stress levels, and the relationships between the influencing parameters iss, tss/tf and tf were analysed. The anodic current density at the tip of the stress corrosion crack was also calculated.
