摘要	The core issue in the study of giant magnetostriction of Fe-Ga alloy thin sheet is to obtain preferential texture through secondary recrystallization. In this work, the evolution of the texture, precipitation, and grain boundary characteristics of an Fe-Ga alloy thin sheet during the annealing process were investigated using XRD, SEM, EBSD, and TEM. The mechanism of the secondary recrystallization of the Goss ({110}<001>) texture in the Fe-Ga alloy thin sheet was analyzed. The results show that the primary recrystallized thin sheet is composed of strong gamma-fibers and has a weak Goss texture. Moreover, high-density MnS and NbC precipitates of size 20-40 nm are dispersedly distributed in the matrix grains after primary recrystallization. The coarsening of the precipitates and a decrease in the volume fraction and density weaken the inhibiting force during the annealing process. The density of the precipitates inside the Goss grains is lower than that of the precipitates in the matrix grains with gamma-texture during the process from primary recrystallization to secondary recrystallization. Before the occurrence of secondary recrystallization, Goss grains do not exhibit a number and size advantages over the matrix grains but are surrounded by higher-energy grain boundaries than the matrix grains. The differences between the Goss and matrix grains in terms of precipitation and high-energy grain boundary characteristics during primary recrystallization provide an additional driving force for the secondary recrystallization of Goss grains. Therefore, a perfect secondary recrystallization of the Goss texture with a saturation magnetostriction coefficient of 250 x 10(-6) is produced in the Fe-Ga alloy thin sheet without the introduction of the surface en-ergy effect using a special annealing atmosphere.
