Abstract

Effects of particle morphology on the tensile-deformation behavior of the oxide dispersion strengthened (ODS) ferritic steels developed for high burn-up operation of light water reactor and super critical water reactor was investigated with tensile tests and microstructural analysis. It is shown that tensile strength and anisotropy in tensile elongation of the ODS steel containing aluminum was decreased compared with those of the ODS steel without alminum. The difference in size distribution of oxide particles could explain the difference in tensile strength of the both ODS steels with applying the Orowan model. It is concluded that optimization of titanium and aluminum contents is useful to improve the strength and anisotropy in the ODS steels.
