Abstract
The primary aim of the research project is to develop a fundamental understanding of the process combination of DED-LB/M and forming with alternating application of the two steps. This can be used for future research to produce tailored components using DED-LB/M and forming. Due to the novelty of this approach, the project content relates to process control and, in particular, to the analysis of thermal and mechanical interactions in the application of the two manufacturing processes. One aim is to quantify the influences of different process strategies on the material properties as well as the temperature fields and profiles in DED-LB/M. In addition, the influence of the combination of the two processes on work hardening and mechanical properties will be analyzed. Based on this, the extent to which the strain hardening introduced during forming can be influenced by recovery or recrystallization during DED-LB/M will be investigated. In addition, the aim is to determine the relationships between the mechanical properties of the as-built test specimen, the formability and the resulting geometric component properties, also in alternating process sequences. This should generate a deep understanding of the forming behavior of structures manufactured using DED-LB/M, which can be used for the design of the combined production chain.
