Synergistic benefits can be derived in alloys by the inclusion of superlattice precipitates. Such benefits include hardening through reduced dislocation mobility in the ordered structure and retained ductility through a coherent precipitate interface. In this research, the concept of superlattice precipitate reinforcement in Ti-Fe alloys is explored. Whilst the lattice misfit between the A2 and B2 phases in binary Ti-Fe alloys is relatively large, it can be reduced with ternary additions. However, ternary Ti-Fe-X systems are poorly documented in the literature. As a result, insufficient information is known about the extent of the A2 + B2 two-phase field and how the lattice misfit may be tuned through compositional modification. In this talk, we will present on the phase equilibria and lattice constants of a range of Ti-rich Ti-Fe-X alloys in order to assess the potential of these systems and facilitate the design of future Ti-based superalloys.
