Microstructure and Creep Resistance of Mg-(8-12 Wt.%) Zn-(2o6 Wt.%) Al Alloys

摘要：

　　The aim of this paper is to investigate the microstructural characteristics and creep resistance ofMg-(8-12 Wt.%) Zn-(2-6 Wt.%) Al alloys in order to get a better overall understanding of these series alloys.The results indicate that the alloys studied with the ratio of Zn/Al concentration between 2 and 3 exhibit high creep resistances,and the alloy ZA124 with the continuous network of τ precipitate along grain boundaries shows the highest creep resistance.The creep resistance of alloys decreases significantly due to e eutectic phase,Φ eutectics and β compounds appearing,especially the creep properties of alloys containing Φ eutectic phase and β phase with lower Zn/Al concentration are obviously inferior to other alloys.
