Abstract Scope |
Designing structural materials with high strength and plasticity has always been challenging. To achieve this goal, researchers have proposed the creation of multiscale heterogeneous structures to manufacture structural materials with excellent overall performance. However, designing multiscale intragranular heterogeneous microstructures, especially in titanium alloys, still faces many difficulties.
In this talk, we introduce novel approaches that combines thermodynamic databases, phase-field simulations, and additive manufacturing for heterogeneous material design and mechanical performance enhancement. Through phase-field simulations, we demonstrate the design of precursor phase-separated organizations and two-step aging processes for designing materials with multiscale layered heterogeneous dual-phase structures. Furthermore, we utilize additive manufacturing techniques to achieve a novel metastable heterogeneous dual-phase organization at the micron scale. This microscale concentration-modulated organization exhibits excellent mechanical properties. This additive manufacturing-based approach creates a new pathway for designing concentration-modulated heterogeneous alloys and can be applied to the design and development of various structural and functional materials. |
