[SY-F4] Phase Field Model of Microstructural Evolution in Metal Alloy for Designing Mechanical Property
Precipitation hardening has been widely employed to improve the mechanical properties of metal alloys. During the precipitation hardening, the supersaturated alloying elements in a solid solution phase form secondary precipitate particles. To design the mechanical properties of metal alloy, the relationship between precipitation conditions and morphology of microstructure of secondary phase should be fully understood. The morphology of microstructure in metal alloy is determined by the composition of the alloy and their intermetallic compounds. Here, we investigate the the morphological evolution of microstructures in metal alloy during precipitation. To simulate the temporal evolution of microstructures, a phase field model is employed. By simulations, the effects of anisotropic interfacial energy and lattice mismatch on the morphology of the microstructure are investigated.
