| Abstract Scope |
This research explored the influence of magnetic field annealing in achieving enhanced mechanical properties alongside microstructural refinement during aging treatments in AA7075 alloy. A custom-built 9-T superconducting magnetic system was employed in heat treating 10 mm thick samples at selected temperatures under 0-, 3-, 6-, and 9-T magnetic field to promote the precipitation and growth of strengthening phases. Mechanical properties measured with the aid of an ex-situ micromechanical and Vickers hardness test showed an improved strength with respect to increasing magnetic field strength across the samples. The size and distribution of the precipitate phases were studied quantitatively by a combination of large area scanning electron microscopy (SEM) and small angle x-ray scattering technique (SAXS) for the four treatments. This work is anticipated to show that magnetic field annealing can be employed in tailoring and enhancing the overall properties of this alloy. |
