Abstract:

Titanium aluminide are intermetallic materials used for lightweight and high temperature application, especially in the aerospace and automotive industry. Recently also it started to be considered as an alternative material for implants in the medical sector. The processability of titanium aluminide present many challenges because of the lack of ductility at room temperature. Additive manufacturing techniques, in particular, electron beam melting (EBM) emerge as suitable solution for the manufacture of different components made of this material. Up to now, few studies have been carried out in order to address the manufacturing challenges and describe the mechanical properties of titanium aluminide components manufactured via additive manufacturing. A review of the state of the art of the processability and characteristics of titanium aluminide is presented in this paper. In the experimental part of the project fourteen different lattice structures samples where produced. The correct fabrication and mechanical characteristic of this samples were analyzed by compression test.
