摘 要：Mg-6 Al-1 Zn-xFe（x = 0,1,3,5 and 7 wt%）alloys were prepared by powder metallurgy and followed by hot extrusion.Majority of Fe element exists as insoluble particles in the alloys.The as-extruded alloys showed higher degradable rates but less stable mechanical properties than as-annealed alloys.Corrosion rate of all the alloys increased with increasing Fe concentration,reaching 2.4 mL cm-2h-1.0.2% yield strength of all the alloys was higher than 150 MPa.In short,Mg-6 Al-1 Zn-xFe alloys have an attractive combination of corrosion and mechanical properties,which holds a bright future for fracturing balls applications.
