An assessment of tensile, irradiation creep, creep rupture, and fatigue behavior in austenitic stainless steels with emphasis on spectral effects

Effects of hydrogen on the mechanical properties of oxide dispersion strengthening steels

“…Since a rather high concentration of hydrogen will be generated in the fusion environment, hydrogen effects on the mechanical properties of high strength ODS steels will be one of critical issues for the development of advanced blanket systems. In a fusion environment, besides the external hydrogen sources such as aqueous corrosion, radiolysis of cooling water etc., the hydrogen production rate in first wall steels by (n, p) transmutation reaction is predicted to be about 0.9 wppm/dpa under 14 MeV neutron irradiation [1].…”

Mechanical characterization of austenitic stainless steel ion irradiated under external stress

“…The ratio of the stress-free specimen was higher than those of the stressed specimen. It is well known that the increase in hardening of solution-annealed material is higher than that of cold-worked material in the same irradiated condition [7]. The degree of hardening did not depend on the external stress level in this test condition.…”

Space fission reactor structural materials: Choices past, present, and future

“…Figure 3 summarizes the stresstemperature design window for 316 stainless steel. 14 This analysis is based on the extensive experimental database on tensile properties and thermal creep 15,16 for stainless steel. The maximum stress limit at 423-823 K is defined as 1/3 ultimate tensile strength (UTS), which is a more conservative design limit than 2/3 of the yield stress for stainless steel.…”
