Description
Incorporating material microstructure, i.e. porosity and phase distribution, into ablation modeling requires the input of quantitative three-dimensional experimental microstructure across multiple length scales. These experimental data are critical to define the initial-state of the material and to validate model predictions of microstructural evolution. This talk will review current experimental capabilities for three-dimensional microstructural analysis based on optical, x-ray and electron scattering. The applicability of the various techniques for measuring surface roughness and three-dimensional microstructure of ablative materials will be discussed. Comparisons will be made between resolution, field-of-view and the non-destructive nature of the techniques.
