Abstract
A metal matrix nanocomposite includes: (1) a matrix including an aluminum alloy; and (2) nanostmctures dispersed in the matrix, wherein the matrix includes grains having aspect ratios of about 3 or less. Manufacturing processes include subjecting the nanocomposite to solidification processing, fusion welding, extrusion, thixocasting, additive manufacturing, and heat treatment.
Claims10
