Abstract Scope |
Zirconium comprises a critical element in the nuclear industry; however, this material oxidizes to form Zirconia at high temperatures. This presents both a source of inefficiency and waste as well as a potential safety hazard. Phase-field modeling is one computational tool that can rapidly simulate the oxidation process and provide insights into its underlying mechanisms. We present coupled phase-field models of fracture and oxidation that can describe the evolution of Zirconia scale as a function of composition and environmental conditions, as well as how this process is linked to fracture at the Zirconium-Zironia interface. We supplement this model with experimental results which both parameterize and provide validation for our proposed modeling framework. This approach presents a computationally simple and ecologically valid method for understanding and characterizing the process of oxidation in Zr and Zr-based alloys.
