MAGNESIUM ALLOY AND PRODUCTION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/157748
Kind Code:
A1
Abstract:
Provided is a magnesium alloy having a thermal conductivity of 75 W/m・K or more and a high specific strength. One aspect of the present invention is a magnesium alloy containing a at.% of AI, b at.% of Ca, c at.% of Mn, and d at.% of D, with the remainder comprising Mg and unavoidable impurities. D has at least one of a rare-earth element (RE), Sn, Li, Zn, Ag, Be and Sc. The magnesium alloy does not contain Si and Sr. C mentioned above satisfies expression 1 below, d satisfies expression 2 below, and a and b are within a range enclosed by the solid line shown in fig. 1. The thermal conductivity is 75 W/m・K or greater. (Expression 1) 0≤c≤0.1 (Expression 2) 0≤d≤1
