Abstract
The present invention provides high strength magnesium alloys consisting essentially of 3 SIMILAR 10 wt.% Zn, 0.25 SIMILAR 3.0 wt.% Mn, and the balance of Mg and inevitable impurities, the high strength magnesium alloy further containing 1 SIMILAR 6 wt.% Al, 0.1 SIMILAR 4.0 wt.% Si, and 0.1 SIMILAR 2.0 wt.% Ca, in order to provide a high strength magnesium alloy having an improved hardness and strength, and an excellent elongation at an ambient temperature. In addition, the present invention provides a method for preparing the high strength magnesium alloy characterized in that a Zn-Mn mother alloy is added to a magnesium melt by a fluxless melting method, and process conditions for working and heat-treating an obtained cast material.
Claims (15)
1. A high strength magnesium alloy comprising: 3 ~ 10 wt.% Zn forming a precipitation phase in the alloy, 0.25 ~ 3.0 wt.% Mn refining the precipitation phase, 1 ~ 6 wt.% Al and the balance of Mg and inevitable impurities, wherein the content of Al is not more than the content of Zn.
2. The high strength magnesium alloy according to claim 1 , further containing 0.1 ~ 4.0 wt.% Si.
3. The high strength magnesium alloy according to claim 2, further containing 0.1 - 2.0 wt.% Ca.
4. The high strength magnesium alloy according to any one of claims 1 to 3, wherein the content of Zn is 5.0 ~ 7.0 wt.%.
5. The high strength magnesium alloy according to any one of claims 1 to 4, wherein the content of Mn is 0.75 ~ 2.0 wt.%.
6. The high strength magnesium alloy according to claim 2 or 3, wherein the content of Si is 1.5 ~ 3.0 wt.%.
7. The high strength magnesium alloy according to claim 3, wherein the content of Ca is 0.3 - 1.0 wt.%.
8. A method for preparing a high strength magnesium alloy comprising the steps of: preparing a magnesium melt under the inert gas ambient atmosphere; adding a Zn-10 ~ 20 wt.% Mn mother alloy to the magnesium melt at a temperature of 670 to 720 °C; adding a shortage Zn to the magnesium melt; forming the Mn and Zn mixed magnesium melt into a cast body; forming the cast body into a billet after homogenization; and working the billet after preheating, thereby forming a wrought body.
9. The method according to claim 8, further comprising the step of adding Al or Ca to the magnesium melt.
10. The method according to claim 8, further comprising the step of adding an Mg- Si mother alloy to the magnesium melt.
11. The method according to claim 8, wherein the step of adding Zn is carried out under a condition in which the magnesium melt has been cooled in a furnace cooling fashion to reduce a loss of Zn exhibiting a high vapor pressure at a temperature at which the alloy is prepared.
12. The method according to claim 8, wherein forming the billet and preheating of the billet is performed at a temperature of 150 to 400 °C for 30 minutes to 2 hours after homogenizing of the cast body at a temperature of 340 to 410 °C for 6 to 12 hours.
13. The method according to claim 12, further comprising the steps of: primarily aging the wrought body at a temperature of 70 to 100 °C for 24 to 96 hours; and secondarily aging the primarily-aged wrought body at a temperature of 150 to 180 °C for 48 hours or more.
14. The method according to claim 13, further comprising the steps of: conducting a solution heat treatment for the wrought body at a temperature of 340 to 410 °C for 6 to 12 hours, prior to the double aging.
15. The method according to claim 13, further comprising the steps of: conducting a stretching of 3 to 7 % for the wrought body, prior to the double aging. For the ppl^ Sanford T T.. Colb & Co. C: 48078
