In this research, two grades of alumina, one at nominally 85% composition and the other at 99.5% were characterized and their dynamic properties determined. To correlate the microstructure and the properties, as well as the failure modes, microstructural characterization using Scanning Electron Microscopy, Energy Dispersive Spectroscopy, X-ray Diffraction, micro-computed X-ray tomography and Electron Backscattered Diffraction were conducted. In addition, Kolsky bar high strain rate compression experiments were conducted, and Knoop hardness values were measured. The post-mortem fragments from the Kolsky bar experiments were also collected and analyzed. The effect of microstructure on the fracture, failure, and dynamic compressive strengths will be discussed.
