The influence of deformation bands on the texture and on the Br/Bs ratio of Fe–20Mo–5Ni-C semi-hard magnetic alloys

Abstract Fe–Mo–Ni alloys show high mechanical plasticity and magnetic properties similar to Vicalloy-II with the advantage of the absence of cobalt in their composition. The addition of carbon has improved the magnetic property H c (coercive force) without significant reduction in B r (remanence). After heat treatment, a coercive force and maximum energetic product as high as 420 Oe and 1.8 MGOe were obtained, respectively. Severe cold rolling deformation prior to magnetic aging improves the magnetic properties B r and H c and increases the ratio B r / B s . This work investigates changes in the texture and in the B r / B s ratio with the development of inhomogeneities during deformation.
