Abstract
A method to form a magnesium article includes: heating materials including magnesium, aluminum, manganese and tin in a furnace to create an alloy having a composition of; the magnesium in an amount greater than or equal to 90% by weight of the materials; the aluminum ranging between approximately 2.0% up to approximately 4.0% by weight of the materials; the manganese ranging between approximately 0.43% up to approximately 0.6% by weight of the materials; and the tin ranging between approximately 1% up to approximately 3% by weight of the materials; chill casting the alloy to create a cast billet; and heating the cast billet at a temperature ranging from approximately 380° C. up to approximately 420° C. and maintaining the temperature for a time period between approximately 4 hours to 10 hours to homogenize element distribution.
