APFIM studies on nanocrystallization of amorphous alloys

This paper reports recent atom probe analysis results of Fe-Zr-B(-Cu, Si, Al) and Al-Ni-Ce(-Cu) nanocrystalline alloys which are fabricated by primary crystallization of amorphous phase. Clustering, partitioning and segregation of alloying elements in the course of primary crystallization have been thoroughly studied by atom probe field ion microscopy (APFIM). Mechanisms of nanocrystallization in these systems are discussed based on these results.
