The microstructure evolution of two additively manufactured β-Ti alloys has been studied in terms of the grain size and morphology. The change in the α morphology and distribution has also been mapped as function of build location. The addition of trace amounts of boron to these additively manufactured β-Ti alloys resulted in significant changes in the microstructure. Depending on the alloy system a grain refinement in the order of 50-100 times was noted. The addition of boron also changed the morphology of the grains from being columnar to more equiaxed. A change in texture was also noted with the addition of boron making it more random. Finally, a change in α morphology was documented in the Ti-Mo system, wherein, addition of boron caused the α precipitates to become more equiaxed than lath-like.
