Abstract
We studied the thermal stability of nanocrystalline (Fe3Si)0.95Nb0.05 and Fe3Si alloys prepared by high-energy ball milling. Alloys were characterized by Mössbauer spectrometry, as well as X-ray diffractometry and transmission electron microscopy. The Nb-containing alloy was considerably more stable against grain growth than was the binary Fe3Si alloy. Mössbauer spectrometry showed that the Nb atoms segregated away from the DO3 ordered domains, probably to grain boundaries, and thus provided a strong suppression on grain growth.
