Probing nanoscale damage gradients in ion-irradiated metals using spherical nanoindentation

Abstract We discuss and demonstrate the application of recently developed spherical nanoindentation stress-strain protocols in characterizing the mechanical behavior of tungsten polycrystalline samples with ion-irradiated surfaces. It is demonstrated that a simple variation of the indenter size (rad...
