Popis:	FeCrAl ODS (oxide dispersion strengthened) alloy with Zr addition was investigated with the main focus on the structure and composition of oxide particles. The results reveal that almost all the small particles (diameter 2 nm) were mainly identified as monoclinic Al2O3 oxides. A core/shell structure is found in slightly large oxide particles. Oxide cores are Al and O while shell regions are enriched in Y. This leads us a promising way to control the structure and size of the oxides and develop the high-performance FeCrAl ODS alloys.
