Recrystallization behavior and magnetostriction under pre-compressive stress of Fe-Ga-B sheets

Li, J. H. and Gao, X. X. and Xie, J. X. and Yuan, C. and Zhu, J. and Yu, R. B. (2012) Recrystallization behavior and magnetostriction under pre-compressive stress of Fe-Ga-B sheets. Intermetallics, 26. pp. 66-71. ISSN 0966-9795


The recrystallization behavior of the rolled Fe 82.2Ga 16.8B alloy sheet suggested that the material was fully recrystallized and the distribution of grain size had become quite heterogeneous after annealing at 650 °C for 1 h. The strong primary recrystallization texture {111}<110> was developed by way of the discontinuous growth of {111}<110> grains. The magnetic field paralleling to the rolling direction promoted the development of η-fiber texture during primary recrystallization. The relation between secondary recrystallization texture and magnetostriction indicated that the cubic texture {001}<100> was obtained in secondary-recrystallized sheets, corresponding to the largest magnetostriction, and a deviation from {001}<100> texture resulted in a decrease of magnetostriction. The 'jump effect' of magnetostrictive strain was obvious when the sample was subjected to compressive stress. Large magnetostrictive strains, λ// of 171 ppm and λ of -146 ppm, were observed for the annealed sheets with the thickness of 0.26 mm under 24 MPa compressive stresses.
