    摘要: A method of processing high strength aluminum sheet is provided. The method may comprise uncoiling a coil of O or F-temper 6xxx or 7xxxx series aluminum alloy sheet, tailored rolling the sheet to form a tailored rolled sheet having at least two different thicknesses, blanking the tailored rolled sheet to form a tailored rolled blank (TRB), hot stamping the tailored rolled blank to form a component, and age hardening the component. The tailored rolling operation may reduce the thickness of the aluminum sheet by up to 60% in selected regions. The method may include a hot stamping process for age hardening aluminum alloys that solution heat treats and quenches the TRB. The method may be used to form lightweight, high-strength aluminum vehicle components having a controlled thickness profile to reduce component part weight.

    摘要: This disclosure details assemblies for mounting and supporting components within battery packs. Exemplary battery packs may include a first battery array, a second battery array positioned adjacent to the first battery array, a crossmember positioned between the first battery array and the second battery array, and a support bracket connected to the crossmember. Together, the crossmember and the support bracket established an assembly. Both the first battery array and the second battery array may be secured to the crossmember, and the support bracket may support a second tier structure above at least one of the first battery array or the second battery array.
