Due to increasing resource scarcity, the efficient use of materials and the reduction of energy input become increasingly important. For the development of new light-weight and resource-efficient components, metallic cellular structures are the essential elements. In the course of this project, cellular structures are investigated regarding their microstructure and defect distribution as well as their quasistatic and cyclic deformation and damage behavior. Concerning the fabrication of cellular structures by additive manufacturing, electron beam melting (EBM) provides more design freedom and opportunities as compared to conventional manufacturing processes.
Duration: 2018 until 2020
