In a collaborative work with the Karlsruhe Institute of Technology, we have investigated the option to establish A2+B2 microstructures in Ti-rich compositionally complex alloys. Based on our previous work on lightweight, oxidation resistance and high-strength Ti-rich solid solution, we have identified the location of the miscibility gap in the Ti-rich corner of the phase diagram. Our study reveals the competition between immiscibility and ordering. By the proper identification of tie lines, deliberate adjustment of microstructures becomes possible.
