Study on magnesium alloys containing zirconium (UDC 669.725: 296): (1st report) On the properties of rolled Mg-Zr alloys

Abstract

With a growing demand for the extensive use of Magnesium alloy materials of good mechanical and thermal properties, studies on the effect of the addition of Zirconium to Magnesium alloys have heretofore been continued pretty laboriously. However, little investigation on of the addition of Zirconium to wrought, especially rolled, Magnesium alloy materials has been reported yet. So that we studied the characteristics of Magnesium rolled sheets containing Zirconium of various amount. The results obtained were as follows; (1) The addition of Zirconium was much effective to refinement of the ingot structure which resulted in the better ingot working. (2) As for mechanical properties, it improved the ductility of the alloy much better than that of Magnesium alone. (3) It raised up the recrystallization temperature. (4) It improved workalilities of Mg-Zr rolled sheet. (5) As to the orientation, its strength decreases with an increase of Zirconium addition. © 1957, The Japan Institute of Light Metals.
