Effect of Yttrium on the Mechanical Properties and Corrosion Resistance of As-extruded AC55Magnesium Alloys with High Ca/Al Ratio AITranslate
Abstract AITranslate
AC55-xY(x=0,0.5,1.0)magnesium alloys with different yttrium contents were prepared by semi-continuous water-cooled casting.The effects of yttrium addition on corrosion resistance and room-temperature mechanical properties of AC55-xY(x=0,0.5,1.0)magnesium alloy were studied by metallo-graphic microscope,X-ray diffractometer,scanning electron microscope,immersion corrosion test and elec-trochemical test.The results show that with the addition of the rare earth metal yttrium,the alloy grains are obviously refined,the eutectic phase changes from continuous structure to semi-continuous network structure,and the mechanical properties of the as-extruded alloy are greatly improved.Compared with AC55alloy,the tensile strength and yield strength of AC55-1.0Y alloy are increased by 19.2%and 17.2%,respectively.With the increase of yttrium content,the corrosion resistance of as-extruded AC55-xY magnesium alloys sequentially increases.The dense and stable corrosion product film formed during the corrosion process plays a vital role in improving the corrosion resistance of the alloy.
