TL;DR: In this paper, the authors reviewed the experimental and theoretical background of this form of metal failure and demonstrated the discontinuous nature of crack growth in α-brass and copper using a combination of acoustic and electrochemical measurements.
Abstract: The transgranular stress-corrosion cracking of ductile alloys (and at least one pure metal) leads to a fracture appearance characteristic of cleavage. The experimental and theoretical background of this form of metal failure is reviewed. The discontinuous nature of crack growth in α-brass and copper is demonstrated using a combination of acoustic and electrochemical measurements. Short-range cleavage of ductile metals is shown to be theoretically possible provided the thin surface film which is responsible for crack initiation has the appropriate properties. The important parameters determining the effectiveness of films in initiating cleavage include the film-substrate misfit, the strength of the bonding across the film-substrate interface, the film thickness and the film ductility. Suitable combinations of these parameters which can lead to micro cleavage are determined by the state of coherency of the interface and the fracture toughness of the substrate. For example, if a ductile de-alloyed l...

TL;DR: Although intergranular stress corrosion cracking (IGSCC) of high-pressure gas pipelines has been known for more than 20 years, a transgranular form (TGSCC) was detected more recently as discussed by the authors.

TL;DR: In this paper, a correlation between the initial open-circuit potential of fresh brittle intergranular fracture surfaces, the copper content of grain-boundary precipitates (GBP), and the plateau SCC velocities of overaged 7079 and 7075 alloys was found.

TL;DR: In this paper, stress corrosion cracking is a phenomenon that is of interest to a wide range of metal users when it occurs under service conditions, often without any prior indication of impeding failure, its effect may be catastrophic.

TL;DR: Ford et al. as mentioned in this paper used the W.R. Whitney Award to predict the cracking susceptibility of ductile alloys in aqueous environments with knowledge of the cracking mechanism.
Abstract: It 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. This complexity can lead to scatter in cracking responses that, in turn, leads to difficulty in predicting the life of engineering structures. F.P. Ford was the 1995 recipient of the W.R. Whitney Award sponsored by NACE International. The present work is taken from his award lecture at CORROSION/95 held in March 1995 in Orlando, Florida. His lecture focused on how these interactions may be predicted quantitatively for ductile alloys in aqueous environments with knowledge of the cracking mechanism. This capability may lead to life prediction of critical structures in, for instance, boiling-water nuclear reactors (BWR).
