Metal matrix composites (MMCs) are materials constituted of at least one metal and a secondary material that serves to reinforce the strength of the original metal, creating stronger compounds than just ordinary metals. MMCs have a wide range of uses, including incorporation into the design of fighter jets and high-end cars as well as in particle accelerators. Currently, the processes for making aluminum-based metal matrix composites and additive manufacturing exist separately; there is no technology for the additive manufacturing of aluminum-based MMCs.

Researchers at Purdue University have developed a new method for the production of high strength aluminum MMCs. The high temperature performance of aluminium-titanium boride (Al-Ti-B) MMCs was increased by using titanium diboride (TiB2) particles in grain refinement in order to increase the effectiveness of grain boundary strengthening, as well as using titanium tri-aluminide (Al3Ti) and scandium (Sc) in the solution and secondary phase strengthening. Finally, the MMCs are made into powder through a standard powder production method for use in applications. This method's production of Al-Ti-B results in the potential for a number of elevated temperature applications.

Advantages:
-Improved grain refinement
-Increased strength
-Better high temperature performance

Potential applications:
-Experimental physics equipment
-Land, air, and space vehicles
-High energy electrical modules
