Abstract

When metallic plates are welded, for example using the Gas Tungsten Arc Welding (GTAW) process, residual tensile stresses may develop in the vicinity of the weld seam. Processes such as Low Plasticity Burnishing (LPB) and Laser Shock Peening (LSP) could be applied locally to eliminate the residual stresses produced by welding. In this study, Alloy 22 (N06022) plates were welded and then the above-mentioned surface treatments were applied to eliminate the residual tensile stresses. The aim of the current study was to comparatively test the corrosion behavior of as-welded (ASW) plates with the corrosion behavior of plates with stress mitigated surfaces. Immersion and electrochemical tests were performed. Results from both general and localized corrosion tests show that the corrosion resistance of the mitigated plates was not affected by the surface treatments applied.

Localized Corrosion of Alloy 22 -Fabrication Effects-

Technical Report Rebak, R

This report deals with the impact of fabrication processes on the localized corrosion behavior of Alloy 22 (N06022). The four fabrication processes that were analyzed are: (1) Surface stress mitigation of final closure weld, (2) Manufacturing of the mockup container, (3) Black annealing of the container and (4) Use of different heats of Alloy 22 for container fabrication. Immersion and Electrochemical tests performed in the laboratory are generally aggressive and do not represent actual repository environments in Yucca Mountain. For example, to determine the intergranular attack in the heat affected zone of a weldment, tests are conducted in boiling acidicmore »« less

Effect of Stress Mitigation on Precipitation Kinetics of Alloy 22 Welds

Conference El-Dasher, B; Torres, S

Understanding the phase stability of Alloy 22 (N06022) is important since the precipitation of tetrahedrally close-packed (TCP) phases over time has been known to adversely affect corrosion and mechanical properties. Prior observations have shown that these phases precipitate during the welding process. After welding, residual stresses due to the solidification and cooling from temperature remain. When the weld cannot be stress-relieved by solution annealing, the application of commercially available stress-mitigation processes such as low plasticity burnishing (LPB) and laser shock peening (LSP) may be used to produce near-surface compressive stresses. This study involved examination of cross-sectional samples of aged 1.25more »« less

Mitigation of Tensile Weld Stresses in Alloy 22 Using Laser Peening

Technical Report Chen, H; Evans, K; Hackel, L; ...

The goal of the Yucca Mountain Project (YMP) is safe permanent disposal of high-level nuclear waste. One of the many technical challenges to this plan is the design of the Engineered Barrier System (EBS) including the waste package that will contain the radioactive waste. One potential failure mode of the waste package is stress corrosion cracking (SCC), which occurs when three criteria simultaneously exist. These criteria are a potentially corrosive environment, a material susceptible to SCC, and the presence of tensile residual stresses at the surface of the material. While many design decisions have been made to attempt to minimizemore »« less
