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://countryscenesaddleryandpetsuppliers.shop/product-category/easy-up-ten-arm-vertical-saddle-pad-rack/
