Title:
MAGNESIUM-BASED ALLOY FOR HIGH TEMPERATURE AND MANUFACTURING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2011/122785
Kind Code:
A3
Abstract:
Provided is a manufacturing method of a magnesium-based alloy for high temperature. The manufacturing method includes melting a magnesium (Mg) or magnesium alloy into a liquid phase, adding calcium oxide (CaO) 1.4 times the weight of a final calcium (Ca) target composition onto a surface of a melt in which the magnesium or the magnesium alloy is melted, forming a targeted amount of Ca in the magnesium or magnesium alloy through a reduction reaction between the melt and the added CaO. Specifically, the amount of Ca formed is in the range of 0.8 wt% to 2.4 wt%, and a final composition of the Mg alloy includes 6.0-8.0 wt% of aluminum (Al), 0.1-0.3 wt% of manganese (Mn), 0.2-0.3 wt% of strontium (Sr), less than 0.04 wt of zinc (Zn), less than 0.9 wt of tin (Sn), and a balance being Mg.
