Shape memory alloys (SMA) gain increasing attention since they are known as promising candidates for numerous industrial applications. For Ni-Ti SMAs thermomechanical processing routes significantly widened potential applications in the last decades. However, processing via additive manufacturing (AM) still is limited although it enables the fabrication of near-net shaped functional materials. Whereas PBF-LB/M of Ni-Ti is discussed more frequently in literature, results on PBF-EB/M of Ni-Ti still remain limited. Current research efforts mainly focus on the characterization of microstructural and functional properties in correlation with the applied process parameters for both processing routes. The present study discusses the impact of an increased carbon content on the functional properties in PBF-EB/M manufactured binary Ni-Ti. The results reveal a high reversibility as well as excellent cyclic stability of the superelastic material properties.
