Abstract: A method for synthesizing a metal matrix nanocomposite (MMNC) is an in-situ synthesis technique for preparing a metal matrix with ceramic reinforcements dispersed homogenously therein. The method includes mixing a base metal matrix material with two or more ceramic-forming elements to form a mixture; blending the mixture; drying the mixture; ball milling the mixture with a plurality of milling balls to form a milled mixture; using induction heating to form a melt flow and induce electromagnetic forces; and initiating a plurality of stirring vortexes in the melt flow to form the metal matrix nanocomposite.
