The effects of Zr addition on some properties of wrought magnesium and its alloys were studied, and the results obtained were as follows:(1) Zr refines the cast structure of magnesium, AZ31, Mg-4% R. E., Mg-4% R. E. -2% Zn alloy and also Mg-6% Zn alloy. The refined structure is stable and do not grow during hot working. Thus, the addition of Zr improves the hot workability of magnesium and its alloys.(2) Zr raises the recrystallization temperature of magnesium about 100°C. The structure after recrystallization is also refined and the grain growth during high temperature heating is prevented remarkably by the Zr addition.(3) Zr decreases the directionality of Mg sheet as rolled, especially after annealing it does more markedly.(4) The strength of wrought Mg and its alloys is little affected by Zr addition.
