Abstract
Ti-5Al-5V-5Mo-3Cr or Ti-5553 is a metastable β Titanium alloy with excellent mechanical properties. Compared to the most common titanium alloy, the α and β Ti6Al4V, even at high cooling rates as present in the laser powder bed fusion process, it establishes an β dominant microstructure which is further highly tunable by heat treatment at lower temperatures than Ti6Al4V.In the scope of this contribution, the processability of T‑5553 is investigated, and the effects of stress relief heat treatment are evaluated. Its influence of achieved microstructures on hardness and impact strength is shown.
