Ti-based alloys have been suggested for commercial applications with a great potential
due to their high strength (~1000 MPa) and good corrosion resistance.
The strength of these alloys can be further increased by producing a nano/ultrafine grained and lamella structured Ti-eutectic. In this paper we focused on the influence of the different cooling rates due to the several casting techniques (arc melting, cold crucible, tilt casting, injection casting and Bridgeman technic) on the Ti-Fe-eutectic alloy. The evolution of the microstructure, the phase constituents, the chemical composition linked to the mechanical properties and elastic constants depending on lamellar growth with multiple orientation will be presented.
To achieve this goal a joint approach, where the detected experimental data are systematically cross-checked against the phase-field simulations with parameters determined from ab initio calculations, is adopted.
