Abstract

Mechanical alloying process has been utilized to synthesis immiscible systems, nanostructured materials, and nanocomposites for decades. In this paper, synthesis and characterization of Al-4.5wt%Cu alloy and its composite, reinforced with TiC, through mechanical milling process are studied. X-ray diffraction technique, scanning electron microscopy and transmission electron microscopy were utilized to characterize the mechanically milled powders. XRD and SEM results indicate the fact that supersaturated solution of Cu in Al occurred during mechanical milling process as a result of mutual diffusion of Al and Cu. In addition, TEM results illustrate the fact that not only mechanically milled powders are nanostructured but also TiC particles had been nanosized after milling process.
