Abstract: The texture evolution and the magnetostriction response of the recrystallized Fe₈₁Ga₁₉ alloy thin sheet cold rolled with different reductions were investigated. It is revealed that the recrystallization texture is composed of Goss (110<001>) and γ (<111>//ND) texture， the characteristic of recrystallization texture is affected greatly by the reduction， attributed to the variation of deformed microstructure and texture. As the cold rolled reduction increases from 60% to 70%， Goss texture and magnetostriction value are enhanced by the increasing shear bands and strong 111<112> texture in deformed matrix. However， when the reduction is 80%， the Goss texture becomes weakened and the γ texture has been enhanced， resulted in a lower magnetostriction， because of the orientation deviation of nucleated grains in shear band caused by the texture variation in deformed matrix and shear bands， as well as more nuclear sites for recrystallized γ grains supplied by grain boundary with a higher storage energy.
