| Abstract Scope |
High magnetic fields, generally coupled with temperatures, provide an enabling disruptive technology to enhance the properties of the alloys. This study investigates the effects of magnetic field on the microstructure and mechanical properties of aluminum alloys. A custom-built furnace system inside the bore of a cryogenic magnet with the capability of reaching 9 Tesla is used to systematically explore heat treatments in precipitation-strengthened aluminum alloys. For example, annealing under a magnetic field accelerates the age hardening curve for the T6 condition in 7075, which is confirmed by electron microscopy and SAXS characterization of precipitate size, shape, and distribution. The effects that a magnetic field is a potential avenue to tailor the microstructure and mechanical properties of Aluminum alloys will be discussed. |
