Successful operation of next generations of radioactive beam facilities depends on the target survival in conditions of intense radiation field and thermo-mechanical solicitations induced by the driving ion beam. Material property degradation due to ion- beam induced damage will limit target lifetime, either by affecting target performance or, by reducing the material resilience. Similar problems are faced by beam protection elements at LHC. Understanding the mechanism of radiation damage induced by ion beam in these materials provides valuable knowledge for lifetime prediction and for the efforts to mitigate performance degradation. On their way through the target material, energetic heavy ions induce a trail of ionizations and excitations, resulting in formation of ion tracks consisting of complex defect structures. We give a review on the ion-induced damage creation in high power target materials, on the structural and thermo-mechanical property degradation and on their recovery in high temperature irradiation experiments.
