Specimens of stainless steel reactor internals were irradiated with 240 keV protons and 6 MeV Xe ions at room temperature. Nanoindentation constant stiffness measurement tests were carried out to study the hardness variations. An irradiation hardening effect was observed in proton- and Xe-irradiated specimens and more irradiation damage causes a larger hardness increment. https://www.roneverhart.com/Castello-di-Amorosa-Il-Barone-Napa-Valley-Cabernet-Sauvignon-2007/
