Strengthening Effect of Y2O3 on AZ92 Magnesium Alloy Using Stir Casting Process
Strengthening effect of Y 2 O 3 on AZ92 magnesium alloy using stir casting process has been investigated. Nominal amounts of Y 2 O 3 (0, 1, 1.5, 2, 2.5 and 3 in wt%) were added into the melt vortex in the form of preformed master powder (Mg–30 wt% Y 2 O 3 ) to improve their wettability with molten A...
