temperature-supported forming; lightweight materials

Due to the requirements to reduce significantly the part weights in car manufacturing, the use of lightweight materials becomes more and more important. Unfortunately, these materials possess often a limited formability. Another challenge which is especially connected with high-strength materials is represented by the high required forming forces and the distinctive springback behaviour. To extend the application oft these materials, it is essential to identify strategies which can contribute to an improvement of their formability. The use of the temperature as a process parameter during forming operations represents a promising solution approach. Temperature supported forming operations offer the chance to improve the formability (achievable strains) and to reduce the required forming forces. Main investigation objectives of the of Fraunhofer Institute for Machine Tools and Forming Technology (IWU) Chemnitz in this field were the proof of the feasibility of temperature-supported forming operations and the determination of appropriate forming windows.
