Abstract
The stress corrosion cracking (SCO) of two types of pipeline steels in a carbonate solution has been eva- luated on the basis of a quantitative statistics of microcracks initiation and growth and of a qualitati- ve evaluation of their character. The influence of a surface microstructure on SCO initiation and quan- titatively evaluated surface SCC damage in different conditions have been the most important results. 1 Introduction Stress corrosion cracking is a significant and dange- rous mechanism of a pipeline damage, besides mecha- nisms caused by external forces and besides material causes. A considerable attention has been paid to the stress corrosion recently. Complexity of the problems and an existence of a relatively unfinished unambigu- ous knowle
