Fabrication route improves the properties of aluminum-based nanocomposites

One challenge in producing strong, elastic and hard-wearing nanocomposites is obtaining an even distribution of the nanoparticles in the metal matrix. Now, researchers at A*STAR have used a process known as friction stir processing (see image) to produce an evenly distributed mix of nanosized aluminum oxide (Al2O3) particles in aluminum. Their technique is a viable new method for manufacturing nanocomposites and has exciting potential for the car, space and defense industries.
