摘要: Abstract This paper deals the effect of Sn and Y additions on microstructure, mechanical corrosion properties AZ91 alloy. It is found that by addition Sn, formation growth discontinuous precipitate get suppressed new intermetallic Mg 2 phase formed. In case together with grain size gets refined, volume 17 Al 12 decreased observed. Improved room high temperature tensile are obtained in as-cast aged added However, maximum for alloy having combined 0.5 wt.% 0.9 wt.% Y. resistance also noticed elements.
