摘要：
This paper deals the effect of Sn and Y additions on the microstructure, mechanical and corrosion properties of AZ91 alloy. It is found that by the addition of Sn, the formation and growth of discontinuous precipitate get suppressed and new intermetallic Mg2Sn phase is formed. In the case of Y addition together with Sn, the grain size gets refined, the volume of Mg17Al12 gets decreased and new intermetallic Al2Y phase is observed. Improved room and high temperature tensile properties are obtained in as-cast and aged Sn and Y added AZ91 alloy. However, maximum properties are obtained for the alloy having combined addition of 0.5 wt.% Sn and 0.9 wt.% Y. Improved corrosion resistance is also noticed with the addition of Sn and Y elements.
