Hybrid compound forging as joining process for aluminum bulk parts and steel sheets

Project title Hybrid compound forging as joining process for aluminum bulk parts and steel sheets (Verbundhybridschmieden)
Project duration 01.03.2017 – 31.12.2018
Press release

To reduce component weight, lightweight constructions and lightweight materials are increasingly applied. Especially in car manufacturing, compounds of steel and lightweight materials as aluminum and magnesium are used. However, the compound is usually generated by an extra joining step, e.g. welding, and presents problems such as increased corrodibility. Therefore, this research project studies the joining of bulk aluminum parts and steel sheets in a combined forming and joining process.

In this research project, a material bond between a bulk aluminum part and a steel sheet shall be generated by forming. The connection is to be made by zinc as plumb to prevent the generation of brittle intermetallic phases. By simulating the process and experimental tests, a suitable process field shall be identified. In a subsequent step, the hybrid part will be formed further to evaluate to what extend the compound is suitable for further processing. The research project is carried out in cooperation with the Institute of Welding and Machining of TU Clausthal.
