MAGNESIUM ALLOY BOARD AND PREPARATION METHOD THEREFOR

WIPO Patent Application WO/2015/126054

A1

The purpose of the present invention is to provide a strip cast magnesium alloy board, wherein the solidification range of a magnesium alloy is controlled by adding, on the basis of a Mg-Al alloy system, an alloy element such as manganese (Mn), tin (Sn), calcium (Ca) or misch metal (Mm), thereby controlling the segregation fraction generated in a strip casting process, and thus the magnesium alloy board has excellent mechanical properties compared with a conventional magnesium alloy board. A magnesium alloy board for strip casting according to the present invention is a Mg-Al-Mn-X (X= Ca or RE) alloy system comprising Al in an amount of more than 3.0 wt% and less than or equal to 10.0 wt% and 0.1-3.0 wt% of Mn, and comprising 0.1-5.0 wt% of Ca or 0.1-5.0 wt% of a rare earth metal and the balance of magnesium and inevitable impurities, and a Mg-Al-Sn-X (X=Ca or RE) alloy system comprising Al of 3.0-10.0 wt%, 0.1-6.0 wt% of Sn and 0.1-0.3 wt% of Mn, and comprising 0.1-5.0 wt% of Ca or 0.1-5.0 wt% of a rare earth metal and the balance of magnesium and inevitable impurities, and thus the segregation fraction of the board is less than or equal to 2.5%.
