Effects of Gd on Microstructure and Corrosion Resistance of Mg-Gd-Y-Sm-Zr Rare Earth Magnesium Alloys AITranslate
Abstract AITranslate
The effect of Gd content on corrosion resistance of Mg-Gd-Y-Sm-Zr rare earth magnesium alloys was investigated by weight loss method. The microstrueture and corrosion morphology of the alloys were observed by optical microscope （OM） and scanning electron microscope （SEM）. And the alloys and their corrosion products were analyzed by XRD. The results show that after heat treatment, Mg-Gd-Y-Sm-Zr rare earth magnesium alloys are consisted of primary α-Mg matrix and precipitated phases of MgsGd and Mg24 Ys. With the increase of Gd content, the alloy grains become finer and the precipitated phases gradual- ly increase. The alloy corrosion rate increases at first and then decreases as Gd content increases, and Mg- 12Gd-2Y-1Sm-0.5Zr alloy has the best corrosion resistance.
