“…4 The roller bearings failed by the development of vertical cracks in a six-year period since they had been installed in the renovated Thelwall viaduct over the M6. Root-cause analysis following metallurgical investigations showed the interaction of atmospheric corrosion with stressing conditions that contributed to the cause of failure.…”

“…Even when structures are physically observed to be in a poor state of repair, such as cracked or leaking, genuine surprise is still expressed when a sudden failure or collapse occurs which may impact economically and tragically result in loss of life. [1][2][3][4][5] Many lessons can be learned from corrosion failures. Sadly, a major cause of corrosion failures is a misunderstanding or complete ignorance by designers and engineers of the changes in performance of materials as they interact with their service environment.…”

Lessons and solutions learned from the forensic investigation of corrosion failures need to be applied throughout the lifecycle of structures. Avoiding misplaced solutions during both design and operating phases relies upon a disciplined and professional forensic approach for all corrosion failure investigations. This paper sets out the elements of the approach and explains how lessons can be learned to prevent future corrosion failures. In particular it describes the macroscopic and microscopic methods required for accurate identification of corrosion failure mechanisms and successful root-cause analysis.
