AB  - In times of climate change, reducing emissions is a key aspect of the research done in the transportation industry. As one of the most important lightweight materials, aluminium occupies a crucial role in this regard. By increasing the functional properties of current aluminium alloys, manufacturers could, therefore, decrease the component weight, thereby reducing emissions. The weight canbe lowered by either utilizing a more lightweight design or alternatively substituting iron-based components for the aluminium ones. It is challenging to process high-strength aluminium alloys with additive manufacturing because they are prone to hot-cracking. “Defect-free” manufacturing can, therefore, only be accomplished by using complex additions such as nano particles or rareearth elements. Due to their documented resistance against hot-cracking as well as their mechanical properties, Al-Ni-alloys based on the α-Al + Al₃Ni eutectic system are promising candidates for investigationwith additive manufacturing.Within this thesis a comprehensive characterization of the microstructural and mechanical propertiesof Al-Ni-alloys in the additive manufactured state is being conducted for the first time. Also, the effect of selected strengthening agents on additively manufactured components is being investigated. The following alloys are taken into consideration in the scope of the thesis: AlNi7.5,AlNi7.5Cu0.5, AlNi7.5Cu2.0, AlNi7.5Zr0.5 and AlNi7.5Mg1.0Si0.5 (values refer to Wt.
