文摘

Mg2Zn11 phase newly forms and precipitates by adding Mg into Zn-Cu alloy. Yield strength increases by 99.7% with 1 Mg addition, indicating obvious strengthening effect of Mg for Zn-3Cu alloy. Ranging from 11.4 to 43.2 μm year-1, the degradation rates of Zn-3Cu-xMg alloys are more suitable for clinic application. The cytocompatibility of Zn-3Cu is enhanced apparently by Mg addition.
