Abstract:
Complex metallic alloys (CMAs) are new possible candidates for reinforcing agents with excellent technological potential. The β-Al3Mg2 belongs to this new category of intermetallics. β-Al3Mg2 nano particles were synthesized by mechanical milling (MM) of Pre-alloyed CMA intermetallic ingot in attritor ball mill. Then differentamont of CMAs nanoparticles varied from 0 to 20% (by weight) were added to Aluminum matrix powder.Consolidated samples were prepared by hot pressing of blended composite powder. Phase and Microstructural characterization were performed applying X-ray diffractometer (XRD), optical microscope (OM) and scanning electronmicroscope (SEM) equipped with energy dispersive X-ray (EDX). The results confirmed the formation of uniform distributed reinforcement in nanocomposites with finer microstructure by addition of CMA reinforcement.
