Production of 9%Cr-Al-Zr ODS Steels

The goal of the project is to produce sample sets of oxide-dispersion strengthened steels, with varying compositions, using advanced manufacturing equipment and techniques. These ODS steels differ from traditional ferrous alloys as they contain nano-sized oxide particles that are dispersed throughout the body of the steel. These dispersions help strengthen the steel as they are much stiffer and harder, and they maintain these properties at high temperatures. Because of the included participates, these steels cannot be manufactured using traditional methods as the oxide particles cannot bond with the metal base. Instead these materials must be formed from a mix of powders that are compressed and heated. The facilities available for this type of manufacturing are limited, and the advanced manufacturing facilities at the University of Science and Technology Beijing specialize in the production of these ODS steels. At the end of this research project, a set of ODS steel samples with varying concentrations will have been manufactured and processed. Additionally, a draft of a research paper will have been completed and data from mechanical testing and electron microscope imaging will have been collected […]
