Abstract

On one hand lightweight sheet materials are characterized by high specific strength but on the other hand, they are limited in the design of sheet metal products. To extend the range of producible geometries, special forming processes at elevated temperatures have been developed. For describing the forming behavior at elevated temperatures or to design forming processes, the knowledge of relevant system parameters like flow stress, friction conditions and contact heat transmission coefficient is assumed. Additionally experimental results are presented to highlight the potential of sheet metal forming processes at elevated temperatures.
