Anisotropic Inter-granular Corrosion Behaviors and Microstructures of AlMgSiCu Alloy Sheets Made by Thermal-Mechanical Treatments
文献摘要：
This study investigates the microstructure and local corrosion behavior of an A1-Mg-Si-Cu alloy,which has been subjected to cold-rolling with different deformation strain ratios (DSRs) and followed by artificial aging.Accelerated corrosion tests show that peak-aged samples with a small DSR (5-10％) are sensitive to inter-granular corrosion (IGC) along both the nor-mal and rolling directions.When the DSR increases to medium strength (20-40％),IGC sensitivity decreases along both directions and corrosion propagates anisotropically.When the DSR is 60-80％,IGC sensitivity along the normal direction continues to decrease,but increases along the rolling direction,indicating pronounced corrosion anisotropy.Microstructural characterization reveals the decreased IGC sensitivity is mainly attributed to a reduction in element segregation at high-angle grain boundaries and the kinked and discontinuous grain boundary corrosion paths.The increased IGC sensitivity along the rolling direction could be related to the significantly flattened grains.
