Journal ArticleDOI
Combined effect of special grain boundaries and grain boundary carbides on IGSCC of Ni–16Cr–9Fe–xC alloys
TL;DR: In this article, an intergranular stress corrosion cracking (IGSCC) was investigated using interrupted constant extension rate tensile tests in a primary water environment at 360°C, where thermal-mechanical treatments were used to increase the fraction of special boundaries from approximately 20-25% to between 30 and 40%.
Journal ArticleDOI
The effect of grain boundary character distribution on the high temperature deformation behavior of Ni–16Cr–9Fe alloys
TL;DR: In this paper, the authors test the Thaveeprungsriporn model for the dependence of creep rate on the coincident site lattice (CSL) fraction, and they find that the hardness in the vicinity of CSLs is greater than that near HABs, and the grain-averaged hardness increases with the fraction of contiguous CSLBs.
Journal ArticleDOI
The role of stress in the efficacy of coincident site lattice boundaries in improving creep and stress corrosion cracking
Bogdan Alexandreanu,Gary S. Was +1 more
TL;DR: In this paper, the authors highlight the importance of deformation in the SCC behavior and show a direct correlation between IGSCC and creep rate via the fraction of CSLBs, as well as a cause and effect relationship between grain boundary deformation and cracking.
Proceedings ArticleDOI
The Stress Corrosion Cracking Behavior of Alloys 690 and 152 Weld in a PWR Environment
TL;DR: In this article, the authors present tensile property data for Alloy 690TT and Alloy 152 welds in the temperature range 25-870°C and showed significant environmental enhancement, while those for Alloy 152 were minimal.
Journal ArticleDOI
Cracking behavior of thermally aged and irradiated CF-8 cast austenitic stainless steel
TL;DR: In this article, the combined effect of thermal aging and neutron irradiation on the cracking behavior of CF-8 cast austenitic stainless steel, crack growth rate (CGR) and fracture toughness J-R curve tests were carried out on compact-tension specimens in high-purity water with low dissolved oxygen.
