“…Nowadays, magnesium alloys are widely used in automotive and aerospace fields because of their excellent properties: low density and high‐specific strength . But people hope that the application of magnesium alloys will not be limited to that, and in order to further extend their scope of application in engineering, many researchers focus attention to get the magnesium alloys that have a good balance of mechanical properties and corrosion resistance . So, the research of magnesium alloys should not be just their mechanical properties but also their corrosion behaviors .…”

The effect of eutectic structure and long period stacking ordered (LPSO) structure on the corrosion resistance of Mg 95.5 Gd 3.5 Zn 1 alloy has been investigated. The eutectic structure and LPSO phase were obtained by different heat treatments and their corrosion behavior and microstructures were examined by immersion test, electrochemical measurement, and SEM. It is suggested that the Mg 95.5 Gd 3.5 Zn 1 alloy containing LPSO phase has a better corrosion resistance than that without LPSO phase. This is due to the smaller accelerating corrosion effect, which is caused by the contact between a-Mg and LPSO phase. Figure 4.

“…5c and d. These phenomena are due to that RE element could control the diffusivity of Al and Mg atoms [13,15]. Since the atomic radius of Y or Gd is larger than those of Mg and Al, thus, Y and Gd which dissolve in the matrix can impede the diffusivity of Al and Mg. As the growths of lamellar DPs and CP laths are controlled by atomic diffusion, the processes of growth for them could be inhibited, which would lead to less lamellar DPs and more globular DPs in DP nodules and thin CP laths in AEZ830.…”

The high temperature deformation behaviour of AZ80 magnesium alloy is studied using tensile tests under strain rates ranging from 0?1 to 20 mm min 21 at temperatures ranging from 300 to 450uC. Microstructure characteristics and forming performance parameters of the alloy, such as fracture morphology and elongation, are obtained. The results show that there are peaks on all of the stress-strain curves at different deformation conditions. The peak stress decreases with increasing deformation temperature and decreasing strain rate. The plasticity of AZ80 Mg alloys increases firstly and then decreases with increasing temperature. Combining this with the analysis of microstructures and fracture morphology, it can be concluded that AZ80 Mg alloys have the best deformation abilities under strain rates ranging from 1 to 10 mm min 21 at 425uC.
