XPS and SEM analysis of the surface of gas atomized powder precursor of ODS ferritic steels obtained through the STARS route
TL;DR: An innovative powder metallurgy route to produce ODS FS, named STARS, has succeeded in atomizing steel powders containing the oxide formers (Y and Ti) and, hence, avoids the mechanical alloying (MA) step to dissolve Y in the matrix as mentioned in this paper.
