Abstract

Permalloys were successfully fabricated by melt drag casting in the present study, and their variation of microstructure and consequent magnetic properties were investigated as a function of Si contents and annealing temperature. The increases in Si content and annealing temperature resulted in the increases of grain size and amount of $Ni_3Fe$ ordered phase. Both the grain size and $Ni_3Fe$ ordered phase controlled by Si and annealing temperature had a important role on permeability of permalloys.
