摘要: Nearly single-grain-oriented Fe–Ga thin sheets with a sharp Goss (0 1 1)[1 0 0] orientation have been developed through rolling and annealing processes. Annealing of rolled samples at 1200 °C under sulfur atmosphere produced abnormal (0 1 1) grain growth, covering ∼98% the sample surface. Compared previous results from anneals argon, anneal resulted in acceleration growth ∼79% increase observed magnetostriction, 163 to 292 ppm, for same protocol.
