Description:
Vehicle weight reduction has been identified as one of the most effective ways of achieving reduced energy consumption and CO 2 emissions in the automotive industry. Aluminium has been used as a lightweight replacement to steel in the automotive industries for many years. In addition to the high specific strength, the formability of high-strength sheet aluminium is increased significantly at elevated temperatures. New manufacturing technologies that allow forming of high and ultra-high strength aluminium alloys have emerged recently. One such technology is HFQ ® - solution heat treatment, forming and in-die quenching which combines material tempering with mechanical deformation. In this article, firstly, HFQ ® Technology is used when forming a uniform thickness blank and, secondly, further benefits are shown when combining the HFQ ® technology with friction stir welding. The friction stir welded AA6082 tailor welded blanks (TWBs), with gau...
