Novel Titanium-based Lattice Block Structures

Lattice Block Materials (LBM) are innovative periodic cellular materials that derive their outstanding mechanical performance from a structure of highly ordered internal triangles, rather than the properties of the parent material. To date, they have been successfully cast for many ferrous and non-ferrous metals, but not reactive metals such as titanium and gamma titanium aluminides. As titanium is a critical aerospace material, and gamma is a key candidate for many future aerospace systems, TiTech International, Inc. proposes to use its unique casting production technology to manufacture prototype titanium-based LBM in this SBIR Phase I effort. The goal is to produce titanium and g-TiAl LBM as near-net shape and affordably as possible, while meeting performance and properties requirements for future aerospace systems.
