Abstract

New results regarding the relationship between the nanostructural formation and glass transition behavior in the Cu-free Fe-Nb-B alloys were presented. Results show that although the nanocrystallization of the Cu-free Fe-Nb-B alloys is most likely to be due to a high homogeneous nucleation rate in the supercooled liquid regime as well as retarded growth rate induced by a large redistribution of Nb between the primary bcc crystallites and the amorphous matrix, the origin of the high homogeneous nucleation rate above T_g in this alloy system remains unknown.
