| Abstract Scope |
The demand for stronger and lighter alloys in engineering applications has prompted the designing of new titanium alloys. However, the potential for enhancing the strength-ductility balance in traditional titanium alloys is limited. To overcome this, we propose a novel approach called "alloys of alloys" or "grand alloys" for alloy design. In this paradigm, alloys, rather than pure elements, serve as the ingredients. Using direct energy deposition, we simultaneously deposit multiple families of Ti alloys, including α+β and metastable β-Ti alloys. Operando X-ray diffraction studies reveal the emergence of orthorhombic and FCC Ti phases during the solidification. Through mechanical and microstructure characterizations, we investigate the deformation behavior of these alloys, considering factors such as local chemical heterogeneities, lattice distortions, and the coexistence of multiple (metastable) phases. This research seeks to redefine titanium alloy design and enhance the mechanical properties of these grand alloys using the unique capabilities of additive manufacturing. |
