| Abstract Scope |
Oxide dispersion-strengthened steels are known because of their superior corrosion properties at high temperatures which favors them for future applications in the next generation nuclear systems and blanket materials for fusion power systems.
The critical point of the ODS steels with nano oxides successful fabrication is the powder prefabrication. Therefore, the main goal of this work is to analyze how various parameters of mechanical alloying influences microstructural and corrosion properties of the austenitic ODS steels. The austenitic 316L stainless steel with the addition of Y2O3 were manufactured from powders prepared under different conditions (time and intervals of mechanical alloying). The corrosion resistance of the materials in terms of microstructural changes was analyzed, and the main factors affecting corrosion behavior of the austenitic ODS steels were systematically studied.
