EFFECT OF PROCESS ON THE RISE OF TEXTURE IN MAGNETIC IRON SHEETS

In spite of poor mechanical properties and low electric resistivity, p ure Iron sheets are more and more used in electrical engineering becau se of their high working induction, related to high magnetization to s aturation. Preferential texture, such as {100}<0kl>, may further incre ase the advantage of these laminations. A process based on ferritic ho t rolling allows pure iron sheets about 0,40 mm thick to be produced, with a marked texture component misoriented around {100}<001>, consist ent with 7.5 - 8.5 kJ/m(3) in final torque peak magnitude M1. In compa rison with today's ''non-oriented'' sheets (M1 approximate to 5 kJ/m(3 )), magnetic properties are significantly improved, giving for example 1.85 to 1.95 T in induction for a 5000 A/m applied field.
