Abstract : Mechanically alloyed aluminum has not lived up to its initial expectations and very little progress has been made in understanding, controlling and improving this material over the last decade. The complexities of the reactions that occur in this material are presented in terms of our present state of knowledge. This current understanding is linked to the mechanical properties of the material. It is necessary that an understanding of the mechanisms regarding the role of oxygen and carbon or hydrocarbon in the material be obtained before further development is undertaken. Once an understanding of the inherent reactions taking place in these materials is determined, then major advances in research and development will occur resulting in an unlimited potential of engineered materials.
