Developing Aluminum-Based Metallic Glass Alloys for use in the Additive Manufacture of High-Toughness Aerospace Components

The additive manufacture of metal components from powder feedstocki.e. the net-shape, three-dimensional forming of a component, layer by layer, from a computer filehas gained popularity in the last nearly three decades, evolving from a method of rapid prototyping to rapid manufacturing. These methods are inherently far-from-equilibrium and present a significant, economical method to fabricate bulk quantities of net-shpae metallic glass. The proposed work will develop aluminum-based metallic glass alloys with ultra-high specific strength specifically for additive manufacturing.
