| Abstract Scope |
Topologically complex materials, including but not limited to additively manufactured lattice materials or gyroid structures, are of great interest due to their ability to meet the structural requirements of a part but with significantly reduced weight. However, in general, these topologically complex structures tend to be designed with the material constrained, homogeneous, and isotropic. The potential to introduce spatially varying materials states, through composition and/or microstructural control, offers a new variable when optimizing structures. This talk will present novel ways to control the microstructure by site-specific thermal histories to achieve desired properties and performance. The alloy in which this will be demonstrated is Ti-5553, with evidence of the potential for generalizing this approach demonstrated in other Ti-based alloys. |
