Patent ID: 7297310

Claim:
A method of producing a nanocomposite, comprising the steps of: a. producing a metal powder of spherical particles with nano surface metal oxides comprised of a metal inside of said particles and a metal oxide layer on the outside of said particles of said metal powder, wherein said metal oxide layer of said spherical particles is quantitatively controlled from a volume percent of nano phase metal oxides needed in said particles, which is defined by a symbol N M and is specified by: N M =1−(1−2 T/D ) 3 , where T is a thickness of the metal oxide layer, and D is an average size of said particles; b. producing a powder mixture comprising a metal alloy element powder of particles and said metal powder of spherical particles with nano surface metal oxides; c. having consolidating performed to said powder mixture first to form a compacted mixture comprising a metal alloy powder of spherical particles with nano surface metal oxides having said metal alloy inside of said particles and a metal oxide layer on the outside of said particles of said metal alloy powder, wherein said metal alloy powder is formed from combining said metal powder with said metal alloy element powder; said consolidating subsequently performed to said compacted mixture to form a composite billet; and d. having a metal working performed to said composite billet to form said nanocomposite, wherein said outside layer of the metal oxides of said metal alloy powder of spherical particles is broken in the processes of making said nanocomposite, and breaking of said metal oxide layer happens during said consolidation step and subsequent metal working step, and broken metal oxide layer is uniformly distributed in a metal matrix resulting in a homogenous nanocomposite.
