Abstract

We have investigated, using transmission electron microscopy (TEM), high resolution electron microscopy (HRTEM) and image processing, the early stages of the mechanical alloying process of a mixture of zirconia and yttrium oxide powders. We focused our investigation to two regions: to a grain boundary region and to the region of stacking faults near grain boundary. Fourier filtering revealed on the atomic level one possible sequence of alloying that occurred in the grain boundary and on stacking faults.
