Microstructure evolution, magnetostrictive and mechanical properties of (Fe83Ga17)99.9(NbC)0.1 alloy ultra-thin sheets

Prospects of Using Fe-Ga Alloys for Magnetostrictive Applications at High Frequencies

“…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.…”

“…In addition, an important parameter is the initial structure of the sample that is subjected to rolling. For example, the authors of [58] propose to use secondarily recrystallized sheets with Goss texture as a workpiece for further rolling (also with a medium deformation degree) and primary recrystallization. This leads to a large proportion of the {100}<001> cubic texture (more than 90%), an optimal grain size, and a good combination of magnetostriction and mechanical properties in ultrathin sheets (Fe 83 Ga 17 ) 99.9 (NbC) 0.1 with a thickness of about 0.1 mm.…”
