Abstract: A titanium-tantalum alloy having a titanium wt % ranging from 10% to 70% and wherein the titanium has a body centered cubic structure. A method of forming a titanium-tantalum alloy, the method comprising the steps of: (a) slicing a 3D CAD model of a part to be formed into a plurality of 2D image layers; (b) preparing a homogenous powder mixture of titanium powder and tantalum powder; (c) dispensing a layer of the powder mixture onto a processing bed; (d) performing powder bed fusion of the layer of the powder mixture according to one of the 2D image layers in one of: a vacuum environment and an inert gas environment; and performing steps (c) and (d) for each of the plurality of 2D image layers in succession.
