    Abstract: An energy absorber according to various embodiments can include a structure having a predetermined cross-sectional profile. A hollow profile is formed within the structure. The pre-determined cross-sectional profile of the structure is configured based on a deceleration-time profile that includes a first period and a second period. The first period is defined by a substantially sharp and linear increase in magnitude of the deceleration of an impact until a maximum deceleration value is achieved. The second period is defined by a rapid decrease in the magnitude of the deceleration.

    Abstract: Methods suitable for forming complex parts from work-hardened sheet materials of limited formability are described. The formability of the work-hardened sheet is enhanced by forming at elevated temperature. The forming temperature is preferably selected to minimally undo the effects of work hardening so that the formed part is of higher strength than a like part formed from an annealed sheet. The method is applicable to age-hardening and non-age-hardening aluminum and magnesium alloys.

    Abstract: An aluminum alloy that can be cast into structural components wherein at least some of the raw materials used to produce the alloy are sourced from secondary production sources. In addition to aluminum as the primary constituent, such an alloy includes 5 to 14% silicon, 0 to 1.5% copper, 0.2 to 0.55% magnesium, 0.2 to 1.2% iron, 0.1 to 0.6% manganese, 0 to 0.5% nickel, 0 to 0.8% zinc, 0 to 0.2% of other trace elements selected from the group consisting essentially of titanium, zirconium, vanadium, molybdenum and cobalt. In a preferred form, most of the aluminum is from a secondary production source. Methods of analyzing a secondary production aluminum alloy to determine its constituent makeup is also disclosed, as is a method of adjusting the constituent makeup of such an alloy in situations where the alloy is out of tolerance when measured against its primary source counterpart.

    Abstract: A method of resistance spot welding a steel workpiece and an aluminum or aluminum alloy workpiece together includes several steps. One step involves inserting a cover between the aluminum or aluminum alloy workpiece and an adjacent welding electrode. In another step, the adjacent welding electrode is pressed against cover, and another opposed welding electrode is pressed against the steel workpiece at a weld site. In yet another step, electrical current is passed between the welding electrodes, passed through the cover, and passed through the workpieces in order to initiate and grow a molten weld pool within the aluminum or aluminum alloy workpiece.
