Description
Summary:Specimens were heat treated and deformed by drawing up to a total deformation of 80%. The magnetic properties were measured in axial and in radial directions. By increasing deformation, coercive force is increased in axial direction and decreased in radial direction. Remanence and energy product increase with the deformation up to a deformation, which depends upon the time of spinodal decomposition. The anisotropy in remanence is proportional to the elongation by drawing while the anisotropy in coercive force is proportional to the ratio of initial and actual diameter of the deformed rod. It is concluded that the anisotropy in remanence depends upon the length of spinodal phases, while the coercive force depends upon the diameter of these phases or more probably upon the magnitude of stresses produced by the accommodation of the lattice of spinodal phases. Only axial stresses produce a beneficial effect on magnetic properties.
