Environmentally Assisted Crack Growth in Structural Alloys.

Abstract

Environmentally assisted crack growth (namely, stress corrosion cracking and corrosion fatigue) in structural alloys is one of the principal factors that determine the durability and reliability of engineering structures. Quantitative understanding of the micromechanics for cracking and of the processes that control crack growth, and modeling of crack growth response in terms of these micromechanisms and controlling processes are essential for the development of new and improved alloys and of more, reliable methods for life prediction. Research supported, in part, by the Office of Naval Research and Lehigh, over the past two and one-half decades has played a major role in transforming the activities in this area from that of screening and qualitative characterization of the phenomena to that of quantitative assessment and scientific understanding. Keywords: Environmental effects; Fracture mechanics; Crack growth; Corrosion fatigue; Stress corrosion cracking electrochemistry; Corrosion; Modeling; Steels. (JS)
