Oxide dispersion-strengthened alloy - Wikipedia

ODS steels are commonly produced through ball-milling an oxide of interest (e.g. Y 2 O 3, Al 2 O 3) with pre-alloyed metal powders followed by compression and sintering of the material.It is believed that the nano-oxides enter into solid solution with the metal during ball-milling and subsequently precipitate during the thermal treatment to yield the ODS steel.
