| Abstract Scope |
With the projected increase in the consumption of aluminum alloys, there is a growing interest in finding ways to strengthen aluminum alloys in shorter time frame to reduce the overall energy requirements. Since the mechanical properties for aluminum alloys like AA7075 are predominantly determined by the formation of precipitates during the artificial aging process, this study focuses on how choice of time, temperature and the application of a magnetic field during annealing changes the evolution of these precipitates. The effects from a magnetic field between 0-9 Telsa during natural aging, and artificial aging between 120°C & 170°C on their precipitation’s characteristics like size, composition, number density, shape and distribution were analyzed using atom probe tomography (APT) and small-angle x-ray scattering (SAXS). The mechanical properties were analyzed using tensile and Vickers hardness testing. The applications of magnetic field to tailor the microstructure and mechanical properties of aluminum alloys will be discussed. |
