TL;DR: In this article, the authors investigated the corrosion and stress corrosion cracking susceptibility of 316L stainless steel exposed to 550°C and 600°C supercritical water and found that increasing the test temperature reduced the corrosion resistance.

TL;DR: In this article, the compressive forces generated by voluminous grain boundary corrosion products were investigated by measuring the forces of under-aged, over-aged and peak-aged aluminum-lithium (Al-Li) alloy 8090 (UNS A98091) in plate and sheet form.
Abstract: Exfoliation of aluminum-lithium (Al-Li) alloy 8090 (UNS A98091) in plate and sheet form was studied by measuring the compressive forces generated by voluminous grain boundary corrosion products. The forces were shown to be related closely to grain shape, with more elongated microstructures generating higher forces. Aging treatment of the alloy also was a factor. Corrosion product forces were ranked in the order: under-aged > over-aged > peak-aged. High susceptibility of the over-aged temper in 8090 differed from that of conventional, precipitation-hardened Al alloys and was attributed to the formation of anodic phases in the Li-containing material. Stress corrosion tests were performed on the plate using double-cantilever beam specimens. The sheet was tested under constant load in the through-thickness direction. KISCC values, the limiting values of stress intensity for stress corrosion to occur, were compared with the maximum corrosion product forces and supported the proposition that exfoliatio...

TL;DR: In this paper, a specially designed setup was used to apply a constant load to a thin sheet sample of AA2024-T3 and, using microfocal X-ray radiography, to observe in situ the resulting intergranular stress corrosion cracking (IGSCC) from the exposed edge of the sample.

TL;DR: In this paper, a constant deflection device designed for use within a transmission electron microscope (TEM) was used to investigate the change in dislocation configuration ahead of a crack tip during stress corrosion cracking, and the initiation of stress corrosion microcracking.

TL;DR: In this paper, stress corrosion cracking of as-quenched 4340 and 3.5NiCrMoV steels was studied under hydrogen charging conditions, with a cathodic current applied to the gauge length of specimens subjected to Linearly Increasing Stress Test (LIST) in 0.5M H 2 SO 4 solution containing 2.5g/l arsenic trioxide (As 2 O 3 ) at 30°C.
