Abstract
This study investigates how a magnetic field affects the α/γ transformation in Fe–Co alloys, particularly its entropy of transformation. Pure Fe, Fe–9.5 at% Co alloy and Fe–19.2 at% Co alloy were analyzed by differential scanning calorimetry in a magnetic field. Both the latent heat and the α/γ transformation entropy for pure Fe and Fe–Co alloys decreased in a magnetic field. These reductions were more pronounced as the Co concentration increased and as the magnetic field strength increased.
