Journal ArticleDOI
Nano-oxide particle stability of 9-12Cr grain morphology modified ODS steels under neutron irradiation
TL;DR: In this paper, a 9-12Cr composition of ODS steels based on modified grain morphology and incorporation of recrystallization heat treatment and martensitic transformation process into previous tube fabrication methods were developed for improving strength anisotropy in hoop and longitudinal directions of cladding tubes.
Journal ArticleDOI
Microstructural changes of neutron irradiated ODS ferritic and martensitic steels
TL;DR: In this paper, three types of modified ODS steels were irradiated in the experimental fast reactor JOYO for investigation of the irradiation-induced microstructural changes.
Journal ArticleDOI
Microstructural development of a heavily neutron-irradiated ODS ferritic steel (MA957) at elevated temperature
TL;DR: In this article, microstructural observation was performed on a neutron-irradiated oxide dispersion strengthened (ODS) ferritic steel with emphasis on oxide behavior, including phase stability under irradiation at elevated temperature (∼973 K).
Journal ArticleDOI
Ring-tensile properties of irradiated oxide dispersion strengthened ferritic/martensitic steel claddings
TL;DR: In this article, the effects of fast neutron irradiation on ring-tensile properties of the oxide dispersion strengthened (ODS) ferritic/martensitic steel claddings with improved microstructural isotropy from recrystallization and α-γ phase transformation were investigated.
Journal ArticleDOI
Phase stability of oxide dispersion-strengthened ferritic steels in neutron irradiation
TL;DR: In this article, microstructural observation and microchemical analysis of oxide dispersion-strengthened ferritic steels were carried out by neutrons up to 21 dpa and showed that the original high dislocation density did not change after neutron irradiation.
