Abstract

It is now well established that irradiation can trigger displacive and order disorder phase transitions in metals and alloys. Recent works have clearly shown that these transitions can also exist in irradiated ceramics. The elementary mechanisms leading to these structural modifications will be discussed in two large gap materials: pure monoclinic zirconia and ZnAl2O4 spinel. The irradiation can strongly affect their structures and their microstructures, leading to a nanostructuration. This can present potential useful consequences for tailoring their physical properties.
