Synthesis and Mechanical Properties of a Novel Al/Β-Al<sub>3</sub>Mg<sub>2</sub> Nanocomposite Prepared by Mechanical Alloying Process
Abstract
<jats:p>Complex metallic alloys (CMA) are new crystalline intermetallic phases representing an upcoming field in materials science. The β-Al<jats:sub>3</jats:sub>Mg<jats:sub>2 </jats:sub>intermetallic compound belongs to this new class of materials. Different amounts of pre-alloyed β-Al<jats:sub>3</jats:sub>Mg<jats:sub>2</jats:sub> nanoparticles (from 0 to 20 wt.%) were mixed with aluminum matrix powder and then co-milled in attrition ball mill for 10 hours. Consolidated samples were prepared by hot pressing of blended composite powders. Microstructural characterization, applying an optical microscope (OM) and scanning electron microscope (SEM) equipped with an energy dispersive X-ray (EDX) analyzer confirmed the formation of uniformly distributed β-Al<jats:sub>3</jats:sub>Mg<jats:sub>2</jats:sub> nanoparticles in the matrix. Furthermore the results indicated that, increasing the amounts of β-Al<jats:sub>3</jats:sub>Mg<jats:sub>2</jats:sub> nanoparticles leads the matrix grain size to be reduced. Effects of reinforcement contents on mechanical properties of nanocomposite samples were also investigated via hardness, compressive and wear tests. The results revealed that with increasing reinforcement content in the matrix, mentioned attributes of the composites are significantly improved.</jats:p>
