For more than two decades, aluminum-matrix composites have been made by different methods including casting [1–9], spray atomization and codeposition [9,10], pressure-infiltration of porous ceramic preforms [11], and powder metallurgy techniques like densification of mixtures of metal and ceramic powders [12–17], or of composite powders made by mechanical processing [13,18–34]. The mechanical properties of these composites are influenced significantly by the quantity and mode of distribution of the reinforcements and also by the nature of the interfaces between the reinforcements and the matrix. In this context, the use of mechanically processed composite powders for producing sound aluminum matrix composites or other metal-matrix composites (MMCs) should be considered as a very promising and commercially viable technique since the starting composite powders are characterized by a uniform distribution of reinforcement particles [2,8,29,32].
