Texture and magnetostriction in rolled Fe-Ga based alloy

The addition of Nb was used to improve ductility during rolling process. The (Fe81Ga19)+1at.%Nb sheet with thickness of 0.6 mm was prepared by conventional rolling, including hot rolling and cold rolling. Results that demonstrate the rolled texture, recrystallization texture and magnetostriction of (Fe81Ga19)+1at.%Nb sheets are presented in this work. The as-rolled sheet had {111} and near {001}<110> rolling-texture grains, and had magnetostriction only as 26×10-6. A near {011}<100> texture and a {001}<100> texture were formed in recrystallized sheets which were water quenched after two hours annealed at 1250 °C and1300 °C, and their magnetostriction (3/2) s were 106×10-6and136×10-6 respectively.
