Book Description
Corrosion fatigue is a generic term that is used to describe the phenomenon of cracking (including environment-enhanced fatigue crack growth) in materials under the combined actions of an applied cyclic stress and a corrosive (aggressive) environment. Quantitative characterization and understanding have been hampered by the complexity of the problem, difficulties in separating the effects associated with crack initiation and crack growth, and by the absence of a truly interdisciplinary attack of the problem. With the development of fracture mechanics technology and sophisticated techniques such as Auger electron spectroscopy and low-energy electron diffraction analysis, quantification of environment-enhanced fatigue crack growth has now been placed on a reasonably firm basis in terms of both steady-state and transient responses. Understanding of the chemical processes that control environment-enhanced fatigue crack growth is beginning to emerge from coordinated mechanical, metallurgical, and chemical studies. A fundamental approach that underlies these studies and recent progress using this approach are described. Areas and directions for future research are discussed.

Book Description
Corrosion fatigue (CF) is a generic term that is used to describe the phenomenon of cracking (including environment enhanced fatigue crack growth) in materials under the conjoint actions of an applied cyclic stress and a corrosive (aggressive) environment. It has been recognized as an important cause for failure of engineering structures. Characterization and understanding of corrosion fatigue are essential to service life prediction, fracture control, and the development of fatigue resistant alloys. Quantitative characterization and understanding have been hampered by the complexity of the problem, difficulties in separating the effects associated with crack initiation and with crack growth, and the absence of truly interdisciplinary attack of this problem.

Environment Enhanced Fatigue Crack Growth in High-Strength Steels
Author: R. P. Wei
Publisher:
ISBN:
Category :
Languages : en
Pages : 57
Book Description
The current state of understanding of the phenomenology and mechanism(s) for corrosion fatigue of high-strength steels is reviewed. Particular attention is directed towards corrosion fatigue in hydrogen and in water/water vapor environments. Available experimental data indicate that fatigue crack growth in high-strength steels is influenced by loading variables, such as frequency, stress ratio and waveform in regions above and below KIscc. The influences of these variables are directly attributed to interactions with the external chemical environment. Possible synergistic interactions and their relation to chemical reaction kinetics are indicated. Pertinent information on oxygen-metal and water-metal reactions is summarized. Initial results from a coordinated program of study for determining the water-metal reaction kinetics and the kinetics of crack growth on a single high-strength steel are discussed. (Author Modified Abstract).
