Abstract

Current additive manufacturing of aluminum alloy restricted to AlSi10Mg and AlSi12 alloy. But it has limitation for structural application. Structural aluminum alloy additive manufacturing associated with formation of oxide, porosities and reflectivity problems. This Navy SBIR Phase I program will develop innovative EBM/DMLS /LENS system compatible engineered aluminum powders and fabrication of porosity free high strength (equivalent to 7050), high fracture toughness , stress corrosion cracking (SCC) resistant structural aluminum component by additive manufacturing for aircraft application and repairing of damaged components. This program will reduce the time required to acquire out-of-production parts for Navy. Phase II will continue to develop this materials and will fabricate more specific components for Navy.
