Change of Inclusion and Mechanical Properties of Magnesium Alloy during Vacuum Melting


Article Preview

Rare earth was added in foundry magnesium alloy in vacuum melting. Analysis and measurement showed that the quantity of inclusions was decreased and the mechanical properties were improved. The size of crystal grain was decreased by 59%, the yield strength was increased by 38% and elongation percentage was increased more than 7 times. On the basis of this experiment, the approaches of improving the mechanical properties of magnesium alloy were brought up.
