Abstract

This study explored the influence of magnetic field annealing in achieving enhanced mechanical properties in terms of yield strength and microhardness in 7075 aluminum alloy. A custom-built 9 Tesla (T) superconducting magnetic system was employed during the aging of the samples at 120 °C without (0-T) and with (3-T) magnetic field to promote the precipitation and growth of strengthening phases. Mechanical properties measured with the aid of micromechanical tensile and Vickers hardness tests showed a 9% improved yield strength and 12% increase in hardness with respect to increasing magnetic field strength to 3-T. The difference in the yield strength for the 0-T and 3-T samples was then explained with yield strength calculation models. This work thus reveals that applying magnetic field during the aging of 7xxx aluminum alloys can help tailor and enhance the hardness and tensile properties of this alloy.
