Secondary recrystallization of Goss texture in one-stage cold rolled Fe–Ga thin sheets via a large rolling reduction

Preparing Fe–Ga sheets with excellent magnetostrictive coefficients by rolling and annealing methods can greatly promote the development of high-efficiency devices. 0.3 mm thick thin sheet was produced one-stage large-reduction cold method without intermediate annealing. Trace V Nb elements addition improves formability precipitating a large number (Nb,V)C particles. The evolution precipitation, microstructure, texture, in investigated. microstructure primary recrystallization is composed homogenous distribution fine grains an average grain size about 22 μm. composite inhibitors MnS precipitates particle 40∼80 nm suppress matrix effectively. texture consists strong γ peak at {111}<112> relatively {114}<481> texture. secondary Goss occurs temperature 900 °C completed 1100 combined effects existing inhibitor several millimeter-sized accompanied small oriented were obtained after °C, its measured magnetostriction value 238 ppm. present work proposes promising routine to produce high-performance sheets.
