Partitioning of Co during crystallisation of Fe-Co-Nb-B(-Cu) amorphous alloys

Abstract:

Partitioning behaviour of alloying elements during the primary crystallisation of both Fe18Co60Nb6B16 and Fe39Co39Nb6B15CU1 alloys has been studied using three-dimensional atom probe (3DAP). Cu rich clusters were found in the Cu-containing alloy, and they provided nucleation sites for the primary alpha-Fe(Co) particles. In the Cu clusters, concentration of both Fe and Co was greatly decreased. In both Cu-containing and Cu-free alloys Nb and B were depleted in the alpha-Fe(Co) particles and en...
