Role of scandium addition to microstructure, corrosion resistance, and mechanical properties of AA7085/ZrB2+Al2O3 composites
Abstract
<p class="MsoNormal">The effect of varying amounts of scandium (Sc) on the mechanical performance and corrosion resistance of aluminum alloy (AA7085) composites reinforced with Zirconium diboride (ZrB<sub>2</sub>) and Aluminum oxide (Al<sub>2</sub>O<sub>3</sub>) nanoparticles was investigated. The specimens were made using an in-situ process with varying amounts of Sc up to 0.5 wt%, and their microstructural behavior, corrosion, and mechanical properties were explored in detail. Phase structural analysis revealed the successful incorporation of ZrB<sub>2</sub> and Al<sub>2</sub>O<sub>3</sub> into the matrix through in-situ synthesis, ranging from 30 to 61.7 nm. In addition, HRTEM and XRD analysis displays the Al<sub>3</sub>Zr prominence observed with 0.1 wt% Sc content, transforming to Al<sub>3</sub>(Sc, Zr) in the 0.3 wt% Sc composite, and finally becoming Al<sub>3</sub>Sc with 0.5 wt% Sc. Corrosion analysis revealed that the 0.3 wt% Sc composite exhibited fine Al<sub>3</sub>(Sc, Zr) precipitate phases that enhanced corrosion properties. The Sc addition leads to a significant improvement in the mechanical properties of AA7085/ZrB<sub>2</sub>+Al<sub>2</sub>O<sub>3</sub> composites. The ultimate tensile strength of 678 ± 5 MPa for 0.5 wt% Sc under the hot rolled and T6 aged condition was achieved. The optimum content of Sc in AA7085/ZrB<sub>2</sub>+Al<sub>2</sub>O<sub>3</sub> composites has identified both corrosion and mechanical properties enhancement at 0.3 wt% and 0.5 wt%, respectively.</p>
