Thermal and Microstructural Dependence of the Initial Permeability of Co60Fe18Nb6(B,Cu)16 Alloys

The thermal and microstructural dependence of the initial permeability of Co60Fe18Nb6B16-yCuy (y = 0, 1) alloys have been studied. The comparison of kinetics and microstructural data of the two compositions indicate the existence of a Cu-clustering phenomenon prior to the nanocrystallization for the...
