Abstract
Official abstract text for this publication.
Magnesium alloys comprising a long period stacking order (LPSO) phase having an 14H-i or an 18R-i structure are provided. The alloys comprise magnesium as a majority element, a first alloying element that is larger than magnesium and a second alloying element that is smaller than magnesium. The first alloying elements include non-rare earth elements.
First claim
Opening claim text (preview).
What is claimed is: 1. A magnesium alloy comprising a long period stacking order structural phase having a 14H-i structure with a Mg 71 X L 8 X S 6 composition or having a 18R-i structure with a Mg 59 X L 8 X S 6 composition, wherein X L comprises a non-rare earth alloying element selected from Ca, Th, Sr and Pa and X S comprises a second alloying element selected from Zn, Al, Cu, Ni and Co, further wherein if X L is Ca, X S is Zn, Al or Cu; if X L is Sr, X S is Zn; and if X L is Pa, X S is Co, and wherein the alloy is free of rare earth elements. 2. The alloy of claim 1 , wherein X L is Ca and X S is selected from Al, Zn and Cu. 3. The alloy of claim 2 , wherein X L is Ca and X S is Zn. 4. The alloy of claim 1 , wherein X L is Sr and X S is Zn. 5. The alloy of claim 1 , wherein X L is Pa and X S is Co. 6. The alloy of claim 1 , wherein X L is Th and X S is selected from Zn, Cu, Ni and Co.
