Title:
NON-COMBUSTIBLE MAGNESIUM ALLOY AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2021/117909
Kind Code:
A1
Abstract:
Provided is a combination of additive elements for a magnesium alloy, which can improve an ignition point while preventing the occurrence of internal oxidation during dissolution. One aspect of the present invention is a non-combustible magnesium alloy which contains A, B and Be in amounts falling within the ranges that satisfy formulae 1 to 3, with the remainder comprising Mg and unavoidable impurities, wherein A represents an element that is likely to be formed into an oxide compared with magnesium and comprises at least one element selected from Ca, Sc and RE (a rare earth element), and B represents an element that is less likely to be formed into an oxide compared with magnesium and comprises at least one element selected from Al, Zn, Mn, Sn, Ag and Sr. (Formula 1) 0.3 at% ≤ A ≤ 10 at%
(Formula 2) 0 at% ≤ B ≤ 11 at%
(Formula 3) 0.003 at% ≤ Be ≤ 0.1 at%
