Since nanocrystalline materials were first proposed by Gleiter et al. and as a result of their attractive properties, nanocrystalline materials of numerous compositions and structures have been prepared by different techniques among which mechanical attrition (MA) is an easy and effective method. In recent years synthesis of nanocrystalline composites, or nanophase composites have been studied extensively. The main methods used to synthesize nanophase composites by MA are mainly alloy power and ceramic powder together to form homogeneously distributed nanocrystalline metal/ceramic composites and milling element powders under atmosphere or medium to form metal/ceramic composites by reaction between elements and medium. Actually MA of immiscible systems may lead to the formation of a nanophase composite if two components can hardly dissolve into each other. In this paper mechanical alloying is studied for the immiscible Pb-Al and Fe-Cu systems.
