| Abstract Scope |
This project investigates using Object Oriented Finite Element Analysis Version 2 (OOF2), an open source FEM program developed and support by NIST, to determine the thermal properties of composite ceramic microstructures with 3 and 4 phases. The compositions evaluated include alumina-ceria-spinel 3-phase composites, and YSZ-alumina-spinel-monazite 4-phase composites, with differing amounts of second phases to determine the effect multiple phases have on the thermal properties of the composite. Secondary and backscattered scanning electron microscopy (SEM) images are used in conjunction with energy-dispersive x-ray spectroscopy (EDS) to provide a map of the different phases. Values for thermal conductivity, modulus of elasticity, and coefficient of thermal expansion for each phase are applied to individual phases within the composite. OOF2 is used to predicate the heat flux, composite thermal conductivity, and thermal stresses when a temperature gradient is applied and results compared to physical measurements of thermal conductivity. |
