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. |

1. A method of forming a tailor-welded blank (TWB) comprising:
fabricating the TWB by welding a first sheet of aluminum to a second sheet of aluminum; and improving a formability of a weld created by the welding by:
heating the TWB to at least a solidus temperature of the first sheet;positioning the TWB in a die set; andclosing the die set on the TWB to form the TWB into a part while simultaneously quenching the part. |
