The 3MA-quantities Mmax2, Hcf, M2 were measured for different directions of the steel strips with respect to the magnetization directions and shown as "magnetic pole figures". The results were compared with x-ray pole figures. A good correlation was obtained betweeen the magnetic and x-ray pole figures. This paper dealt with the experimental results obtained from specimens of low-alloy steel grades with small carbon content (deep drawing steels) and well-defined textures, characterized by the deep drawability values rm. The measurements were performed using the direction dependence of the 3MA-quantities. At the present stage of development, Barkhausen noise- and incremental permeability profiles were recorded by means of a rotating yoke-transducer, i.e. by varying the magnetic direction. Laboratory equipment, the IzfP-3MA-prototype and automated probe manipulation systems were used.
