Influence of Al addition on the microstructure and mechanical properties of Zr-containing 9Cr-ODS steel
TL;DR: In this article, two oxide dispersion strengthened (ODS) steels with compositions of 9Cr-ODS (9Cr- ODS) and 9Cr 3Al ODS (9 Cr-3Al ODS-ODS-Al) were fabricated by hot isostatic pressing (HIP) and the microstructures and precipitates of the ODS samples were characterized by scanning electron microscopy (SEM), electron backscatter diffraction (EBSD), and transmission electron microscope (TEM).

Structural materials challenges for advanced reactor systems
TL;DR: In this paper, the authors give a brief overview of various materials that are essential to establish advanced systems feasibility and performance for in pile and out of pile applications, such as ferritic/martensitic steels (9-12% Cr), nickel based alloys (Haynes 230, Inconel 617, etc.), oxide dispersion strengthened ferritic and martensite steels, and ceramics (SiC, TiC, etc.).

Characterization of high temperature creep properties in recrystallized 12Cr-ODS ferritic steel claddings
Shigeharu Ukai,Takanari Okuda,Masayuki Fujiwara,Toshimi Kobayashi,S Mizuta,Hideharu Nakashima +5 more
TL;DR: In this article, the high temperature strengthening mechanism of previously manufactured 12Cr-ODS ferritic steel claddings was clarified, and the grain boundary sliding associated with grain morphology was considered to be controlled by the near Σ11, Σ and Σ19 coincidence boundaries with a (110) common axis.
