“…It should be noted that the creation of a texture of this type in a bcc alloy is a rather difficult task. In recent years, attempts have been made to actively solve this problem by studying the mechanisms of texture formation in Fe-Ga [53,56] and the selection of deformation and recrystallization parameters [52,53,55,[57][58][59][60][61][62][63][64][65]. In terms of technology, there are two approaches to creating desirable texture in Fe-Ga sheets.…”

“…For this reason, an alternative direction is being developed, namely, the creation of the necessary crystalline texture due to primary recrystallization, which does not lead to the formation of large grains [53,54,58,59,62,63,65,78]. The main problem with this approach is the much weaker <100>//RD (rolling direction) texture compared to secondary recrystallization.…”

Fe-Ga is a promising magnetostrictive rare-earth free alloy with an attractive combination of useful properties. In this review, we consider this material through the lens of its potential use in magnetostrictive applications at elevated frequencies. The properties of the Fe-Ga alloy are compared with other popular magnetostrictive alloys. The two different approaches to reducing eddy current losses for such applications in the context of the Fe-Ga alloy, in particular, the fabrication of thin sheets and Fe-Ga/epoxy composites, are discussed. For the first time, the results of more than a decade of research aimed at developing each of these approaches are analyzed and summarized. The features of each approach, as well as the advantages and disadvantages, are outlined. In general, it has been shown that the Fe-Ga alloy is the most promising magnetostrictive material for use at elevated frequencies (up to 100 kHz) compared to analogs. However, for a wide practical application of the alloy, it is still necessary to solve several problems, which are described in this review.
