Sharp Goss texture and magnetostriction in binary Fe81Ga19 sheets

Goss ({110}< 001 >) texture development and magnetostriction in binary Fe81Ga19 sheet were investigated. Millimeters-sized Goss grains, covering 80% area of the annealed sheet surface, are produced by secondary recrystallization without effects of inhibitor and surface energy. The micro-texture analysis demonstrates that primarily recrystallized Goss grains have an evident advantage in size and number to be potential secondary nuclei. The grain size distribution of primary Goss grains can induce the continuable abnormal growth until the completion of secondary recrystallization. The obtained magnetostriction coefficient is close to those with the help of inhibitor or surface energy. (C) 2016 Elsevier B.V. All rights reserved.
