Evolution of strength and coercivity during annealing of FeCo based alloys

T. Sourmail


Iron-cobalt alloys are used as soft-magnetic materials in circumstances where a high magnetic saturation is important. There is confusion in the literature about the cause of an observed discontinuity in the variation of strength and coercivity as a function of the temperature at which cold-rolled Fe-Co alloys are annealed. It is shown here using calculations based on published data, that the variety of observations can be reconciled on the basis of grain growth rather than the extent of recrystallisation.
