“…Robertson [60] showed for ion-irradiated austenitic steels, the mechanical properties of the ion-irradiated layer can be isolated from those of the substrate if the indent depth is <0.33t, or ~650 nm for the ion-irradiated specimen considered here. This is consistent with the work of Kasada [25], [26] and Miyazawa [27], who use the inflection point in the squared hardness vs.…”

“…This would render top-down nanoindentation on an ion-irradiated surface rather impractical, as indents made deep enough so as to overcome surface effects may then oversample the softer, unirradiated bulk, while indents made shallow enough to sample the appropriate region in the damage profile will be overwhelmed by surface effects. Recent work [25]- [27] has successfully demonstrated topdown nanoindentation approaches on ion-irradiated materials that account for indentation size effects (i.e. surface effects), damage gradient effects, and softer substrate effects.…”

“…Microstructure-mechanical property correlation is a crucial study to apply the present data to the estimate of radiation hardening and embrittlement. An effort to evaluate mechanical properties using the irradiated specimens in common with the present study is in progress using nanoindentation techniques [15].…”

“…Однако после выдержки в литии значения микротвёрдости этих образцов мало отличаются от исходных значений. Это, вероятно, связано с тем, что в процессе подготовки образцов к испытаниям в жидком металле, когда ампулы с образцами выдерживали при Т = 800 ºС для очистки лития от примесей внедрения, происходит отжиг радиационных дефектов, являющихся причиной упрочнения материалов под воздействием ионных пучков [11,14]. Из таблицы также следует, что микротвёрдость поверхности необлучённых материалов после выдержки в литии несколько уменьшается по сравнению с исходным состоянием.…”
