Correlation among a variety of miniaturized mechanical tests and their application to D-T neutron-irradiated metals

摘要: Abstract Tensile, disk bulge and microhardness tests with miniaturized specimens have been performed on a variety of metals alloys. Both the fracture load test strongly correlate tensile strength. Specimens as thin 0.1 mm generally fulfil requirements for obtaining bulk properties from tests, materials where grain size can be properly controlled. The were carried out Ni, Au. Cu austenitic stainless steel irradiated D-T fusion neutrons RTNS-II. Au showed large increase in yield strength up to factors 7 reduction ductility down 50% by irradiation 1.7 × 10 22 n/m 2 . Ni is about half that Au, decrease small steel. Variation deformation mode increasing neutron fluence has detected optical electron microscopy.
