| Abstract Scope |
Commercial titanium alloys such as Ti-64, which are widely used in additive manufacturing today, have anisotropic properties due to large prior beta grains that develop during additive manufacturing. This research investigates alloying elements that expand the freezing range and induce a columnar to equiaxed transition at rather low alloying content. It has been shown that beta-eutectoid elements including Iron, Nickel and Cobalt at ~3wt% will induce a fully equiaxed microstructure with grains an order of magnitude smaller than in their counterpart alloys. The mechanical properties or these newly developed alloys also shows significant promise, as they have increased strength, as well as similar ductility. Post-build heat treatments also introduce possibilities for different properties and microstructures depending on the desired application. |
