[110] grain growth and magnetic properties of thin grain-oriented 3% silicon steel sheets

[110] grain growth and magnetic properties in thin grain-oriented silicon sheets with ultimately low loss were investigated. A final-annealing at 1150/spl deg/C for 20 min enables us to obtain the thin sheets covered with only [110] grains and consequently the magnetic induction at 800 A/m, B/sub g/ reached 1.9 T.
