Abstract Scope |
The desirability of 5XXX series Aluminum-Magnesium alloys for Naval use is tempered by their propensity to develop Intergranular Stress-Corrosion Cracking (IGSCC). This promoted by the precipitation of an anodic β phase (Al3Mg2) along grain boundaries with thermal exposure, especially for long times at service temperatures. To study the effects of service exposure on sensitization and cracking, 5083 Aluminum from a ship with over four decades of field exposure is examined herein. This work specifically focuses on the interaction of cracking with the microstructure and environment, and tracing the development of cracks with high-resolution tomography. |
