Abstract

The flexibility in design offered by advanced additive manufacturing technologies makes this process more and more attractive for the automotive as well as the aircraft industry, especially for the production of metal components. Nevertheless, while, on the one hand, additive manufacturing paved the way for new design solutions which were not possible before, on the other hand, it represents a new process, which has still not been standardized and, therefore, made exploitable. In this work, the cyclic material behavior of two different metals used for additive manufacturing technologies were evaluated. Small-scale specimens, produced by Selective Laser Melting (SLM) of the Aluminum alloy AlSi10Mg and Inconel® 718 powder, were subjected to Incremental Step Tests (IST) in order to evaluate the cyclic stress-strain behavior of the material. The effects of removed support structures, four building orientations, surface conditions and an additional heat treatment on the cyclic stress-strain behavior of the material were evaluated.
