Influence of Thermal Treatment on Magnetomechanical Damping of 49Fe-49Co-2V Alloy

The 2V Permendur alloy (49Fe-49Co-2V) is very useful for electrical applications requiring high magnetic flux densities. The improvement of its magnetic (maximum permeability, coercive force) and magnetomechanical (damping) properties is achieved by various thermal treatments. The results are discussed according to the influence of order, grain size, internal stresses and d.c. applied field.
