“…As mentioned in Ref. [15], the improvement of deformability of Fe 83 Ga 17 alloy is attributed to the columnar-grained structure induced by directional solidification. Our previous studies have indicated that 2 at% addition of Cr changed the fracture mode of Fe 83 Ga 17 alloy from intergranular brittle fracture into transgranular and resulted in an improvement of the strength and ductility.…”

“…Further details of the preparation method can be found in our previous work. [15] The as-drawn Fe 83 Ga 17 and (Fe 83 Ga 17 ) 98 Cr 2 wires were recrystallized at 1150 • C for 1 h and then quenched to room temperature. The final heat treatment was carried out at 800 • C for 1 h and then followed by quenched cooling.…”

“…Recently, our research group has investigated the preparation and the magnetostriction of Fe-Ga wire. [15] We prepared Fe 83 Ga 17 wires with diameters in a range of 0.5 mm-0.9 mm by hot rotary swaging and warm drawing from the directional solidified rods, and a large magnetostriction of 160 ppm was obtained in the annealed wire. In this paper, we extend our previous studies of the Wiedemann effect of Fe 83 Ga 17 wire.…”

(Fe83Ga17)98Cr2 wires each with a diameter of 0.7 mm are prepared by hot swaging and warm drawing from the casting rods directly, because the ductility of Fe83Ga17 alloy is improved by adding Cr element. The Wiedemann twists and dependences on magnetostrictions of Fe83Ga17 and (Fe83Ga17)98Cr2 wires are investigated. The largest observed Wiedemann twists of 245 s·cm−1 and 182 s·cm−1 are detected in the annealed Fe83Ga17 and (Fe83Ga17)98Cr2 wires, respectively. The magnetostrictions of the annealed Fe83Ga17 and (Fe83Ga17)98Cr2 wires are 160 ppm and 107 ppm, respectively. The maximum of the Wiedemann twist increases with magnetostriction increasing. However the magnetostriction is just one important factor that affects the Wiedemann effect of alloy wire, and the relationship between magnetostriction and Wiedemann effect is a complex function rather than a simple function.

“…In all works it is emphasized that the best magnetostrictive properties bring out in the asquenched from high temperature samples, and the worst -at slow cooling [10][11][12][13][14]. However concerning the atomic structure which is formed at the same time there is some discrepancy.…”

For the first time hydroextrusion process was chosen for Fe-Ga ingots deformation with a gallium content of 19 and 20 at.%. The samples were annealed at 950oC, followed by air cooling. Structure of deformation and primary recrystallyzation were investigated by the method of electron back-scattered diffraction (EBSD). The degree of hydroextrusion deformation achieved was 28 – 42 %. There was not found any crystallographic texture at such degree of deformation. The value of magnetostriction in recrystallization sample was about 100 ppm. Available in literature methods and approaches to creation of the Fe-Ga samples from the point of view of receiving high magnetostriction and also a possibility of machining of the samples are discussed.
