| 1. An article manufactured by a method, the method comprising
providing a nanocomposite material, wherein providing said nanocomposite material comprises
providing a molten material;
providing a nano-sized material, said nano-sized material being substantially inert with respect to said molten material;
introducing said nano-sized material into said molten material;
dispersing said nano-sized material within said molten material using at least one dispersion technique selected from the
group consisting of
agitating said molten material using ultrasonic energy to disperse said nano-sized material within said molten material,
introducing at least one active element into said molten material to enhance wetting of said nano-sized material by said molten
material, and
coating said nano-sized material with a wetting agent to promote wetting of said molten metal on said nano-sized material;
solidifying said molten material to form a solid nanocomposite material, said nanocomposite material comprising a dispersion
of said nano-sized material within a solid matrix, wherein said solid matrix comprises a directionally solidified material
or a single crystal material; and
forming said nanocomposite material into said article.
