ABSTRACT:
An aluminum matrix composite containing evenly dispersed reinforcement particles in the aluminum matrix wherein the contents of oxygen and carbon are controlled so that their volume percentage is not larger than 20% and wherein the contents of the reinforcement particles, oxygen and carbon are controlled so that their volume percentage is not larger than 40%. The control of oxygen and carbon is effected by carrying out the main process at a non-oxidizing atmosphere and minimizing the addition of an anti-seizure agent required to facilitate the mechanical alloying treatment.
