摘要	The corrosion behavior of extruded Nd-free AZ91 and extruded AZ91 + 1.5Nd alloy was investigated by weight loss and electrochemical measurements. The results showed that the extruded A291 + 1.5Nd alloy had higher corrosion resistance compared to the extruded Nd-free AZ91 alloy, which could been explained from point of view of microstructure changes: (1) the significant decrease of twins and dislocation decreased the anodic dissolution rate; (2) the micro-galvanic corrosion was inhibited by the formation of Al(3)Nd phase; and (3) Nd not only increased the percent of Non-Faraday process, but also led to anisotropic feature on the corrosion mechanism.
