The corrosion behaviour ofthe alloy is closely dependent on its microstructure. Under the peak aging condition,the coarse T_2 phase, which is continuously distributed along grain boundary, has solow corrosion potential in comparison with matrix, that makes the corrosion resis-tance of the alloy to be deteriorated by anodic dissolution along grain boundary.
