Novel aluminum-carbon NanoTubes (CNT) micro-composite has been produced by Mechanical Milling (MM) process followed by pressure-less sintering during 3h at 823 K under vacuum. As-sintered specimens were evaluated in their mechanical properties by using a compression test. Yield stress (σy) and maximum strength (σmax) values reached in the composites are considerably higher than those reported for pure aluminum and experimental values found in pure aluminum samples prepared by using the same route. σy and σmax values increase as the CNT content increase as well. Milling time and CNT concentration have an important effect on mechanical properties in final products.
