Abstract Scope |
One of the existing challenges in joining of Ti-6Al-4V and Inconel 718 is the formation of Ti-Ni intermetallic compounds that fail to achieve acceptable mechanical properties for using in hybrid structures. This paper aims to introduce a new interlayer design for Ti-6Al-4V and Inconel 718 Joining by ternary projection diagrams and thermodynamic calculations. Due to the fact that non-equilibrium solidification happens in additive manufacturing processes, therefore classic Scheil-Gulliver and Scheil-Gulliver were investigated, and their ternary phase projections with potential interlayers were plotted. By considering the ternary feasibility diagrams of titanium, nickel, as the base materials and different interlayers, appropriate interlayers were selected to join Ti-6Al-4V and Inconel 718. The findings of this research reveal that implementation of this approach for additive manufacturing processes can pave the way for designing additively manufactured multi-metallic interlayers in dissimilar joining or FGM materials. |
