Preparation of Nanostructured Materials Having Improved Ductility


Project TitlePreparation of Nanostructured Materials Having Improved Ductility
Track CodeU.S. Patent No. 7,699,946 (DOE S-104,970)
Short Description

Los Alamos National Laboratory - Express Licensing Program

A method for preparing a nanostructured aluminum alloy involves heating an aluminum alloy workpiece at temperature sufficient to produce a single phase coarse grained aluminum alloy, then refining the grain size of the workpiece at a temperature at or below room temperature, and then aging the workpiece to precipitate second phase particles in the nanosized grains of the workpiece that increase the ductility without decreasing the strength of the workpiece.
