HOT-STAMPING TAILOR-WELDED BLANKS OF ALUMINUM SHEET

摘要

Forming a tailor-welded blank (TWB) having aluminum sheets includes various elements. For example, a hot-stamping methodology is applied to a welded blank for meeting load and stiffness requirements in tandem to weight efficiency. A TWB can result in improved material utilization, and applying the hot-stamping methodology can improve the formability of the TWB. After forming and subsequent processing, a peak-age heat treatment is utilized such that a lightweight, high strength part may be attained.
