Tantalum is used in titanium alloy. However, there is still little knowledge about the mechanical proprieties of Ti-Ta alloys. And about their fatigue behavior, no documented information is known. The potential applications of Ti-Ta alloys are medical, naval, aerospace. Data related to the Ti-Ta alloys obtained by additive manufacturing is innovative and crucial for developing new Ti-Ta mechanical components. This work studies the additive manufacturing parameters to manufacture the Ti-Ta alloy with a weight percentage of 10% of tantalum and 90% of titanium, each element with 99,9% purity. Vicker's hardness, tensile and fatigue tests were performed. The true and engineering tensile proprieties were obtained. The plastic deformation was characterized. Fatigue behavior study was realized. And the fracture surface morphology was analyzed.
