摘要：
The precipitation behavior of Mg-Al-Sn-Zn alloys was investigated in this study. By artificial aging treatment, maximum hardness values of ATZ821 and ATZ651 alloys were higher than ones of AZ61 and AZ81 alloys without any change in the peak aging time. Based on TEM analyses, it was confirmed that Mg2Sn precipitates formed on edge-tip sides of pre-formed Mg17Al12 precipitates on the basal plane of alpha-Mg matrix. It indicates that Mg17Al12 precipitates play a heterogeneous nucleation sites for Mg2Sn precipitates. In addition, Mg17Al12 and Mg2Sn precipitates could be dramatically refined and homogeneously dispersed by a dilute addition of sodium which caused an increase in maximum hardness value and significant decrease in peak aging time. Unlike previous reports, Mg17Al12 precipitates which could serve nucleation sites for Mg2Sn were refined by a dilute addition of sodium, as a result of which Mg2Sn precipitates were also refined.
