| Abstract Scope |
This talk develops two-dimensional grain growth phase field (PF) models of beta-Titanium (Ti) in the presence of nanoporosity over varying temperatures. Beta-Ti alloys are the bcc allotropic phase and have applications in extreme environments due to their high-strength, corrosion-resistant properties. Understanding microstructural evolution, including grain growth, is essential for predicting how these mechanical properties evolve during extreme service conditions. Previous work has revealed that grain growth of beta-Ti is influenced by nanoporosity. However, the effect of nanopore morphology and distribution on this grain evolution is not well understood. Here, a PF grain growth model based on free energy minimization is executed within MOOSE to explore isothermal grain growth in the presence of variable nanoporosity at temperatures ranging from 900-1400℃. The PF results are validated against experimental data. The resultant model can be used to predict beta-Ti grain growth during novel powder-based synthesis such as magnesiothermic reduction or solid-state advanced manufacturing. |
