| 简介 |
The purpose of the present invention is to provide a strip-casted magnesium alloy panel having excellent mechanical characteristics when compared to an existing magnesium alloy panel by controlling segregation occurring in a fraction generated in a strip-casting process by controlling a coagulation section of a magnesium alloy by adding an alloy element such as manganese (Mn), tin (Sn), calcium (Ca), or mischmetal (Mm) based on an Mg-Al alloy. According to the present invention of the strip-casted magnesium alloy, an Mg-Al-Mn-X (X=Ca or RE) alloy comprises : 3.0-10.0 wt% of Al, 0.1-3.0 wt% of Mn, and 0.1-5.0 wt% of Ca or 0.1-5.0 wt% of a rare-earth metal; and the remaining consisting of magnesium and inevitable foreign substances. An Mg-Al-Sn-X (X=Ca or RE) contains 3.0-10.0 wt% of Al, 0.1-6.0 wt% of Sn, 0.1-0.3 wt% of Mn, and 0.1-5.0 wt% of Ca or 0.1-5.0 wt% of a rare-earth metal; and the remaining consisting of magnesium and inevitable foreign substances. The segregation occurring in the fraction of a panel is not greater than 2.5%. |
