The effect of yttrium on improving the amorphous steel glass formability (GFA) is investigated through chemical analysis during the early devitrification stage by employing energy dispersive x-ray spectroscopy and three-dimensional atom probe techniques. Atomic segregation and partitioning are found to occur in association with the formation of the principal competing crystalline M23 (CB)6 phase. The partitioning of Y from crystallite particles is confirmed, in agreement with first principles calculations. Additionally, the GFA improvement is also attributed to the strong interatomic bonding between lanthanide and metalloids. The role of Y on improving GFA is verified with growth kinetic measurements.
