Evidence of mechanical alloying in ball milled ZrO2-Y2O3 system based on HRTEM image processing analysis

We investigated, using high resolution electron microscopy and image processing, the early stages of the mechanical alloying process of a mixture of zirconia and yttrium oxide powders. We focuse our investigation on the grain boundary region and the region of overlappiung layers of zirconia and yttria. Fourier fgiltering revealed, at the atomic level, one possible sequence of alloying, which occured in the grain boundary and in the overlapping layers.
