Titanium alloys, due to their high strength to weight ratio, proper corrosion resistance and biocompatibility, have been extensively used in aerospace, automotive and medical applications. On the other hand, certain properties, such as high chemical reactivity, high hardness and low thermal conductivity, make them challenging to machine. Therefore, additive manufacturing (AM) processes have gained a lot of attention to produce near-net shape parts from a wide range of titanium alloys. While a lot of studies can be found in the literature for Ti-6Al-4V, knowledge on other titanium alloys in the AM form is still lacking. In this study, the microstructure, as well as tensile and fatigue behavior of three additively manufactured titanium alloys, namely Ti-5Al-5V-5Mo-3Cr, Ti-5Al-5Mo-5V-1Cr-1Fe and Ti-6Al-2Sn-4Zr-2Mo-0.08Si have been evaluated in comparison to the well-studied Ti-6Al-4V. All specimens were fabricated using an EOS M290 laser beam powder bed fusion AM machine.
