Single grain growth and large magnetostriction in secondarily recrystallized Fe–Ga thin sheet with sharp Goss (0 1 1)[1 0 0] orientation

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 a sulfur atmosphere produced abnormal Goss (0 1 1) grain growth, covering ∼98% of the sample surface. Compared with previous results from anneals under argon, the sulfur anneal resulted in the acceleration of abnormal (0 1 1) grain growth and a ∼79% increase in the observed magnetostriction, from 163 to 292 ppm, for the same anneal protocol.
