Aluminum-magnesium-scandium alloy for aerospace additive manufacturing
The patent US12031199B2 describes a novel aluminum-magnesium-scandium alloy characterized by specific compositional ranges and structural features. The alloy comprises scandium (Sc) in the range of 0.23 to 0.37 weight percent, zirconium (Zr) from 0.11 to 0.19 wt%, magnesium (Mg) between 4.1 and 5.6 wt%, manganese (Mn) from 0.2 to 1.0 wt%, and titanium (Ti) in the range of 0.05 to 0.15 wt%. Additionally, the alloy limits the presence of silicon (Si), iron (Fe), copper (Cu), and zinc (Zn) to 0.1 wt% or less, with aluminum (Al) making up the balance. A notable feature of this alloy is the inclusion of at least one primary particle or domain of Al3(Sc, Zr) with dimensions not exceeding 20 micrometers.
The patent further details various optional components and ratios within the alloy, such as the inclusion of trace elements and specific limits on other metals like chromium (Cr) and beryllium (Be). The claims also extend to a wire made from this alloy, which maintains the same compositional parameters and includes additional specifications regarding its diameter, spooling characteristics, and the dimensions of articles formed from the wire. The wire is designed to have an average diameter of 2 mm or less and can be used to create articles with a thickness of at least 0.05 inches, where certain portions of the article can have a height significantly greater than its thickness. This patent outlines a comprehensive framework for the development and application of this advanced aluminum alloy, emphasizing its potential utility in various industrial applications.
