This paper deals with magnetic anisotropy found in hard turned surfaces. The high magnetic anisotropy of the surface after hard turning operations occurs due to severe plastic deformation and high temperature, exceeding the Curie temperature in the cutting zone, followed by rapid cooling. The transformed microstructures of the surface, and stress anisotropy near the surface cause the magnetic anisotropy and magnetic domain reconfiguration. On the contrary, temperatures during grinding usually do not exceed Curie temperature and so the remarkable magnetic anisotropy after grinding operations in not found. The magnetic properties of the studied surfaces are analyzed by Barkhausen noise emission as well as magneto-optical methods. The results of these two techniques are used to study the magnetic anisotropy.
