Assignee:

Novelis Inc. - Atlanta GA

International Classification:

C22F 1/047
C22C 21/08

Abstract:

Described are aluminum alloy products and methods of making aluminum alloy products in which the aluminum alloy products have carefully controlled intermetallic particle density and particle size. Such aluminum alloy products may exhibit favorable formability. Control over intermetallic particle size and density may allow for use of high amounts of recycled source content in aluminum alloy products.

Abstract:

Described are methods of treating surfaces of metal alloy substrates and associated metal alloy products. The methods may include providing an aluminum alloy product having a bulk and a surface and scanning abeam of high energy across the surface. The method may further include applying a liquid layer onto the surface prior to scanning a beam of high energy. The beam of high energy may interact with the surface and/or the liquid layer to form a treated surface. The beam of high energy may interact with the surface and/or the liquid layer to physically modify the at least a portion of the aluminum alloy product to form a treated sub-surface layer.
