ABSTRACT

An additive manufacturing method includes using hydrogenated titanium in forming an object by additive manufacturing, the object having a first microstructure. The method includes heat treating the hydrogenated titanium and, after completing a shape of the object, dehydrogenating the object. The dehydrogenated object has a second microstructure different from the first microstructure. Also, another additive manufacturing method includes forming an object containing Ti--6Al--4V, the object having a first microstructure containing columnar structures along a build direction of the additive manufacturing and the object exhibiting mechanical property anisotropy resulting from the columnar structures. After completing a shape of the object, the method includes hydrogenating the Ti--6Al--4V, heat treating the object containing the hydrogenated titanium, and dehydrogenating the heat treated object. The method reduces mechanical property anisotropy and the dehydrogenated object has a second microstructure different from the first microstructure. More... »
