文摘
- •
In matrix coherent and tiny precipitates have good anodic dissolution resistance.
- •
Alloy elements solubility changed by precipitate size affects corrosion potential.
- •
Discontinuous precipitates at grain boundary degrade intergranular corrosion.
- •
High copper of grain boundary precipitate has low stress corrosion susceptibility.
