Environmentally Assisted Cracking
1999Abstract Environmentally assisted cracking is a generic term that includes various cracking phenomena such as stress-corrosion cracking (SCC), corrosion fatigue cracking, and liquid-metal embrittlement. This chapter describes these cracking mechanisms beginning with SCC and the factors that influence its formation.

Quantitative Prediction of Environmentally Assisted Cracking
Corrosion, 1996It has long been recognized that the stress corrosion cracking (SCC) and corrosion fatigue cracking susceptibility of various alloy and environment systems is dependent upon complex interactions between stress, material, and environmental parameters.

3 Mechanisms of environmentally-assisted cracking
International Journal of Pressure Vessels and Piping, 1989The initial objective of the Mechanisms Subcommittee of the International Cooperative Group on Cyclic Crack Growth (ICCGR) was to define theoretically the maximum crack propagation rate for low alloy steels undergoing fatigue loading in Light Water Reactor environments. This task was prompted by the observation that the current crack growth rate values

Environmentally assisted cracking of aluminium alloys
Materialwissenschaft und Werkstofftechnik, 2007AbstractA short review of the stress corrosion cracking (SCC) behaviour of aluminium alloys is given. Mechanisms of environmentally assisted cracking are outlined. For aluminium alloys, in which stress corrosion cracks propagate predominantly along grain boundaries, anodic dissolution and hydrogen embrittlement have been proposed.

Environmentally Assisted Cracking of Uranium Alloys
2017Abstract Uranium alloys are used in applications requiring dense metals, but they have little resistance to oxidation and corrosion and are susceptible to environmentally assisted cracking, particularly when processed to high strength levels. This chapter describes the conditions under which uranium alloys are most prone to cracking.

Failures of engineering components due to environmentally assisted cracking
Practical Failure Analysis, 2003Examples of failures of engineering components by stress-corrosion cracking, corrosion-fatigue, hydrogen embrittlement, liquid-metal embrittlement, and solid-metal embrittlement are described. Causes of failure include inappropriate materials selection or heat treatment, poor design, and high residual stresses. The examples illustrate how fractographic

Environmentally Assisted Fatigue Crack Growth
1989Modeling of environmentally assisted fatigue (or corrosion fatigue) crack growth in terms of environmental variables and of microstructure is presented. The models serve as a framework for understanding the mechanisms for corrosion fatigue and the crack growth response.

Environmentally assisted cracking of magnesium alloys
2009Fracture mechanics based techniques can be used to study the phenomena of stress corrosion cracking and hydrogen embrittlement and to model the degradation of metallic materials caused by the uptake of atomic hydrogen. Constant extension rate tensile experiments were performed on both smooth and pre-cracked specimens of Mg alloys at various strain ...
