HIGH STRENGTH MAGNESIUM ALLOY AND ITS PREPARATION METHOD |
摘要 |
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. |
