Recovery annealing was studied in Fe-0.7Si electrical steel processed by cold rolling. The samples were annealed at temperatures of 300°C, 400°C, and 500°C for 30, 60, and 90 min in inert nitrogen atmosphere. No samples suffered recrystallization.

Two alloys of nonoriented electrical steel, with 2.45 and 3.3%Si, respectively, had their magnetic properties characterized in an Epstein frame. Hysteresis curves for total, quasi-static, and parasitic losses were plotted and overlapped to identify t
