Project Description

This project, as part of the Research Group - Green Aerospace of the Munich Aerospace e.V. focuses on combining additive and conventional manufacturing methods. These hybrid structures aim to reduce the need for joining techniques and offering potential production cost savings without compromising functionality. The risk of such complex multimaterial combinations lies in the formation of intermetallic phases which could lead to micro- and macro-cracks or lack-of-fusion defects at the interface between the alloys. The project focuses on optimizing the processing conditions of the laser powder bed fusion (LPBF) process, to produce homogeneous and defect-free interfaces. The fabricated structures will be evaluated by means of optical and scanning electron microscopy, mechanical testing and nanoindentation measurements. The influence of post-processing heat treatments on the mechanical properties will also be studied.
