Abstract
A method of manufacturing specialized alloys having specific properties and an alloy made using this method. The methods involve the use of micro and/or nano-sized particles that are mixed into an alloy using a friction stir welding method. The micro and/or nano-sized particles are used to alter one or more characteristics of the alloy in the locations in which the micro and/or nano-sized particles are added. The micro and/or nano-sized particles may be metal particles, non-metal particles, or a combination thereof.
Claims15
A method for creating a specialized alloy comprising:
- applying first particles to a selected area of an alloy, wherein the first particles alter a selected property of the alloy;
- applying second particles to another selected area of the alloy, wherein the second particles alter the selected property of the alloy differently than the first particles;
- mixing the first particles into the selected area of the alloy using friction stir welding;
- mixing the second particles into the other selected area using friction stir welding;
- wherein the first and second particles have a size between about 1.0 nm and about 500 μm.
