Production, microstructure and mechanical properties of two different austenitic ODS steels
TL;DR: In this paper, a two-step milling procedure with the use of ZrO2 milling balls was applied to raise the production yield and to use the abrasion of the ZRO2 as an additional element to facilitate the formation of nano-sized precipitates.

Bimodal Grain Size Distribution of Nanostructured Ferritic ODS Fe–Cr Alloys
TL;DR: In this article, electron-diffraction techniques and atom probe tomography revealed the presence of large particle-free zones in one material, which is, together with the inhomogeneous deformation at short milling times, considered the main reason for the formation of a heterogeneous microstructure.

On the Role of Alloy Composition and Sintering Parameters in the Bimodal Grain Size Distribution and Mechanical Properties of ODS Ferritic Steels
TL;DR: In this paper, a sintered 14Cr-5Al-3W oxide dispersion strengthened steel was produced by mechanical alloying and consolidated by field-assisted hot pressing, and the effect of the addition of zirconia and of the pressure applied during sintering on the final bimodal grain microstructure and mechanical properties was assessed.

Perspective of ODS alloys application in nuclear environments
Shigeharu Ukai,Masayuki Fujiwara +1 more
TL;DR: In this article, the authors reviewed the JNC activities on ODS steel development as "nano-composite materials" and concluded that the ODS-technology development achieved in the field of fast reactors should be effectively spun off to the fusion reactor first wall and blanket structural materials to allow for safe and economical reactor design.
