Sub-surface damage in ground and annealed alumina and alumina-silicon carbide nanocomposites

Abstract:

High-resolution, grazing incidence, X-ray powder diffraction has been used to probe the strain dispersion (microstrain) and diffracting, domain size as a function of depth in alumina and alumina-silicon carbide nanocomposite. The microstrain was high, and of similar magnitude, below ground surfaces in both materials but declined much more rapidly with distance from the surface in the pure alumina than in the nanocomposite. The depth over which significant microstrain was observed was in good ...
