Abstract:
A method for producing high strength aluminum alloy product from powder containing L12 intermetallic dispersoids using high pressure gas atomization to deposit droplets on a substrate prior to complete solidification to form a billet. The sprayed deposit is hot worked using extrusion, forging and rolling to densify the structure by eliminating porosity, improving mechanical properties and to produce different shapes of components.
