Effect of some alloying elements on boiling point of magnesium

The evaporation capacity of alloys differs with temperature, and this is the basis of a new experimental method to measure the boiling points of various kinds of alloys. In the present work, the effects of Al, Zn, Mn and La additions on the boiling point of magnesium have been studied. It is shown that various elemental additions and their varying contents in magnesium alloys have different influences on the boiling point of the alloys. Among these additions, Zn affected the boiling point of magnesium alloys most obviously, followed by Mn, Al and La. The boiling point of Mg-6 wt-%Zn alloy was the highest in the present study, up to 1715 K.
