| Abstract: |
| With the ever-increasing concern about the energy and environment crises, the demand for the automotive weight reduction has been required more than usually expected. The wide application of aluminum alloy sheets with high specific strength in automotive bodies has become an important development direction. Various forming techniques have been introduced to automobile manufacturing due to the low formability of aluminum alloy sheets at room temperature. The paper outlines several special forming techniques for aluminum parts in small batch production, including superplastic forming, sheet hydroforming, and so on. It reviews various heat treatment-stamping integrated techniques for aluminum parts in large batch production, including intermediate annealing-stamping integrated method, warm stamping, stamping in the W temper and hot stamping. Their development history and present situation are outlined. The key issue of the property controlling during forming is stressed for these heat treatment-stamping integrated techniques of aluminum alloy sheets. The advantages and disadvantages of these techniques are also discussed. Finally, the development trend and promising research topics of the aluminum sheets stamping technology are presented for future studies.
