“…In order to produce thin sheets with reasonable robustness and magnetostrictive properties, efforts have been made to produce the textured sheets by rolling and secondary crystallization processes [8][9][10][11][12]. Up to now, the secondary recrystallization, also named abnormal grain growth (AGG), of Goss-oriented ({110}<001>) grains has been considered as the most effective way to achieve the sharp <001> orientation along the rolling direction in the rolled Fe-Ga alloy sheets [13][14][15][16][17][18].…”

Abstract:The effects of initial oriented columnar grains on the texture evolution and magnetostriction in (Fe 83 Ga 17 ) 99.9 (NbC) 0.1 rolled sheets were investigated. The recrystallization texture evolution exhibited the heredity of initial orientations, concerning the formation of cube and Goss textures in the primary recrystallized sheet for the columnar-grained sample. Moreover, the growth advantage of Goss grains was more obvious than that of cube grains during the secondary recrystallization process. Because of the combined effect of this and Nb-rich precipitates as inhibitors, a sharp Goss texture and very large Goss grains were achieved in the secondary recrystallized sheet for the columnar-grained sample. For comparison, the secondary recrystallization in the equiaxed-grained sample was not fully developed although there were Nb-rich precipitates as inhibitors. We think this could be ascribed to the large particle size and premature coarsening of precipitates. Magnetostriction of the secondary recrystallized columnar-grained sheet was up to 232 ppm owing to the ideal Goss texture and quite large grain size. As for the equiaxed-grained sample, the magnetostriction was only 163 ppm in the secondary recrystallized sheet.

Selective abnormal growth behavior of Goss grains was investigated by interrupting secondary recrystallization process in magnetostrictive (Fe 83 Ga 17 ) 99.9 (NbC) 0.1 rolled alloy sheets. The evolution of microstructure and texture was analyzed by electron back-scattered diffraction while ramping the temperature from 1123 to 1353 K. The results indicate that before temperature increasing up to 1203 K, Goss grains had no advantages in size and quantity, and the abnormal grain growth did not occur. Goss grains grew abnormally from about 1218 K due to the inhibitory action of Nb-rich precipitates on normal growth of other orientated grains. The γ-ber texture was the predominant texture before the onset of secondary recrystallization. When the secondary recrystallization got fully development, a sharp Goss texture and an average magnetostriction up to 210 ppm were obtained in the sample annealed at 1353 K.
