Aluminum alloys have been extensively used in the automotive and marine industry due to the advantages of low density, high strength to weight ratio and good corrosion resistance. Major challenge of their application lies in the ability to form deep-drawing shapes. Superplastic Forming is widely used to produce this type of parts. However, high forming cycle time due to the low forming strain rate limits their wide application. The present dissertation focuses on hot forming strategies to produce deep drawing parts from AA5383 aluminum thin sheets. The main objective is to reduce the forming time without sacrificing the part integrity. Firstly, the hot deformation behavior of the AA5383 alloy is experimentally characterized. An experimental...
