Abstract

We investigated, using high resolution electron microscopy and imageprocessing, the early stages of the mechanical alloying processof a mixture of zirconia and yttrium oxide powders. Molar fractionof yttrium oxide was 0.10. We focused our investigation on thegrain boundary region and the region of overlapping layers of zirconiaand yttria. Fourier filtering revealed, at the atomic level, onepossible sequence of alloying, which occurred in the grain boundaryand in the overlapping layers.
