Data for: Characterization of Y-bearing particles in CNS-I-ODS steel fabricated by vacuum induction melting & casting technique

Vacuum induction melting (VIM) & casting is not a common but a promising approach to produce ODS steel with large volume and high throughput. Meanwhile, the Y-bearing particles in the cast ODS steel presented various chemical compositions and wide size distribution.

Thus it is important and necessary to clarify the Y-bearing particle characteristics in the cast ODS steel. In order to determine the distribution characteristics, chemical compositions, crystal structure and size distribution of the Y-bearing particles, CNS-I-ODS was fabricated by adding 1.0 wt.% metallic yttrium into the molten China Nuclear Steel (CNS) during VIM. The results indicated that some banding structures comprised of yttrium oxides and Y-bearing intermetallic compounds formed along rolling direction.
