Role of microstructure in corrosion initiation of a highly-deformed AA2024 wire
Source abstract
Abstract
Abstract Stable pits with H2 evolution preferentially occurred in an annular region surrounding the centre of AA2024 wire. The grain size and intermetallic particles (α-phase, Al7Cu2Fe, Al2CuMg, Mg2Si, Al2Cu) distributions were the same for both regions. However, the annulus had mixed orientations, high angle grain boundaries and microshear bands while the centre was dominated by [111] orientations and low angle grain boundaries with the latter being responsible for its passive nature.
