Model for the hardness-depth relationships of ion-irradiated nanocrystalline metals
Journal of Materials Research and Technology, 2023 In this work, a mechanistic model is proposed for ion-irradiated nanocrystalline (NC) metals to characterize the evolution of hardness as a function of the indentation depth at room temperature and under quasi-static loading condition. At the grain level,
