Microstructural development in non-oriented lamination steels

Effect of annealing prior to cold rolling on magnetic and mechanical properties of low carbon non-oriented electrical steels

“…Finally, after stamping from strip blanks, the laminations are subjected to long term grain growth and decarburization annealing treatment at temperatures below Ac 1 (the ferrite to austenite transformation temperature on heating) [4,[15][16][17]. Alternative processing routes have been reported for production of low core losses electrical steel grades, such as optimized hot rolling, annealing prior to cold rolling and cold rolling in two steps with intermediate annealing [18,19].…”
