| Abstract Scope |
There are many uses of Ti-6Al-4V (Ti-64), ranging from creating aerospace components to being used in implants due to its high strength-to-mass ratio. Additive manufacturing of Ti-64 and other metals has become a topic of intense research interest in the past several years. In this paper, we examine microstructural evolution in additively manufactured Ti-64 as it is heated. Specifically, we use electron backscatter diffraction to look at the grains found in samples of Ti-64. With increasing temperature, we found the defects in the grains to decrease and the grains to coarsen. Growth selection as seen from the free surface reveals information on oriented growth and nucleation. |
