TLDR
In this paper, the influence of materials factors on IGSCC was investigated for simple pure metals with limited materials or metallurgical variables, substructures arising from cold work were targeted as the critical factors assisting IGSC, which otherwise rarely occurs in pure annealed metals.About:

Failure analysis of a copper tube in a finned heat exchanger
H. Peltola,M. Lindgren +1 more
TL;DR: In this article, the authors present the failure analysis of a finned heat exchanger which leaked in the pressure test during commissioning and showed that the failure was a consequence of ant-nest corrosion, as all the experimental findings, together with the copper grade and the tube dimensions were typical of this corrosion mechanism.
Journal ArticleDOI
Failure analysis of copper tube used in a refrigerating plant
TL;DR: In this paper, the failure analysis of a leaked copper tube used in a refrigerating plant for carrying polyol ester oil for lubrication and cooling of compressor bearings was reported.
Journal ArticleDOI
Interactive effect of ant nest corrosion and stress corrosion on the failure of copper tubes
TL;DR: A new opinion is raised in this article, that the interaction of ant nest corrosion and stress corrosion cause the failure of copper tubes, which is a serious problem for air conditioning manufacturers and customers.
Journal ArticleDOI
The effect of the crystallographic texture on intergranular stress corrosion crack paths
TL;DR: In this paper, the authors show that the crystallographic texture is a critical factor that drives the IGSCC crack path and that residual shear strain induced by shear texture (induced by rolling processes) explains the inclination of the cracks at a certain depth and the continuous propagation of cracks along the transverse directions.
Journal ArticleDOI
Inclined stress corrosion cracks in gas pipeline steels: morphology and implications
TL;DR: In this paper, a morphological survey was carried out on 120 stress corrosion cracks (SCC) from an ex service X65 Australian gas pipeline and it was found that the inclined crack path was due to anisotropic residual stress/strains present in the material introduced during pipe manufacturing processes.

Corrosion of ultra-fine grained copper fabricated by equal-channel angular pressing
TL;DR: Corrosion of ultra-fine grain (UFG) copper fabricated by equal-channel angular pressing (ECAP) has been investigated in comparison with that in recrystallized coarse grain (CG) copper as discussed by the authors.
Journal ArticleDOI
Effects of prior cold work and sensitization heat treatment on chloride stress corrosion cracking in type 304 stainless steels
TL;DR: In this article, the effects of prior cold work and sensitization treatment on the stress corrosion cracking (SCC) behavior of Type 304 stainless steels have been studied in chloride solutions using electrochemical tests and magnesium chloride tests with U-bend specimen.
Journal ArticleDOI
A comparison of the corrosion behaviour of polycrystalline and nanocrystalline cobalt
TL;DR: In this paper, the corrosion behavior of polycrystalline and nanocrystalline Co was studied in 0.25 M Na2SO4 solution, and it was shown that grain size reduction has little effect on the overall corrosion performance of Co.
Journal ArticleDOI
The crystallography of stress corrosion cracking in face centered cubic single crystals
TL;DR: In this paper, the transgranular stress corrosion cracking was studied for single crystals of α-brass, copper, and 304L austenitic stainless steel, and it was concluded that the stress corrosion cracks in all systems tested occurred by cleavage.

Effects of cold working path on strain concentration, grain boundary microstructure and stress corrosion cracking in Alloy 600
TL;DR: In this paper, the grain boundary microstructure, strain distribution and stress corrosion cracking (SCC) in one dimensional (1D), two dimensional (2D) and three dimensional (3D) cold worked Alloy 600 were investigated.
