Pitting of aluminium at grain boundaries after ageing

Pitting of aluminium at grain boundaries after ageing

Thin foils of 99-999% aluminium prepared by electropolishing have been found to develop surface pits along the grain boundaries during ageing at room temperature. It is suggested that the pits are formed by a vacancy mechanism, and that they are associated with the initiation of etch attack along th...

Zusammenfassung:Thin foils of 99-999% aluminium prepared by electropolishing have been found to develop surface pits along the grain boundaries during ageing at room temperature. It is suggested that the pits are formed by a vacancy mechanism, and that they are associated with the initiation of etch attack along the grain boundaries of aged pure aluminium.
