Sažetak

High-resolution transmission electron microscope (HRTEM) image processing analysis is used to analyse and to compare the process of ball milling in pure ZrO2 powders and in ZrO2-10 mol % Y2O3 powders. Applying HRTEM image processing to the grain boundary region and other defects, we are able to observe, at the atomic level, a possible sequence of alloying and transition that occur at the grain boundary, in the overlapping layers and on the stacking faults.
