Superplastic Forming of Aluminum.

摘要

Superplastic sheet metal forming allows the production of complex -parts, which are not formable under normal conditions. In the framework of one of the German National Research Foundation (Deutsche Forschungsgemeinschaft -DFG) financed project a new tool for the Superplastic forming of aluminum alloys has been developed. Since the most used forming medium at the Superplastic forming is gas, a theoretical model is used to describe the pneumatic bulge test. For the experimental investigations the Superplastic aluminum alloy AA 5083 - also known as Formall~R545 has been used.
