“…The magnetostriction of the randomly oriented Fe-Ga alloy prepared by copper mold casting is very low [10,13], and the value is a little smaller than that of the directional solidified alloy with the weak <110> preferential direction [14]. The magnetostriction up to 270×10 −6 is obtained for the Fe-Ga alloy rod with <100> preferential direction prepared by directional growth [14].…”

Polycrystalline Fe 83 Ga 17 alloy rods with various amounts of yttrium were prepared by high vacuum induction melting. It is found that yttrium addition has a significant effect on the structure and magnetostriction of Fe 83 Ga 17 alloy. The small addition of yttrium alters the solidification character and the grain shape of Fe 83 Ga 17 alloy, and as a result, columnar grains with the <100> preferential direction are produced. Yttrium addition improves the magnetostrictive performance of the as-cast Fe 83 Ga 17 alloy. The magnetostriction values of the as-cast alloy with 0.32at% and 0.64at% yttrium addition go up to 119×10 −6 and 137×10 −6 under 15 MPa compressive stress, respectively. The energy dispersive spectroscopy (EDS) result shows that almost all of the yttrium atoms exist in the Y 2 Fe 17−x Ga x phase. A small amount of this kind of secondary phase cannot obviously increase the saturate magnetic field.

“…In contrast, V, Cr, Mn, Co, Rh, Ni, Mo, and Al additions reduce the magnetostriction of Fe-Ga single crystals [8][9]. In the case of polycrystalline Fe-Ga materials, Co, Ni, Al, Be, and B additions reduce or slightly enhance the magnetostriction of Fe-Ga alloys [10][11][12].…”

“…A study of substituting additionally Co and Ni for Fe in polycrystalline Fe 85 Ga 15 alloy was also done. It was shown that the magnetostriction of the ternary alloys is similar to that of pure polycrystalline Fe 85 Ga 15 , due to very poor texture [5]. Recently, it was reported that the saturation magnetostriction measured on meltspun ribbon reaches values as high as 2000 ppm, if the magnetostriction is measured along the ribbon length applying a magnetic field perpendicular to the ribbon plane using straingauge method [6].…”

“…In the past several years, Fe-Ga alloys have attracted much attention as potential magnetostrictive materials, being characterized by low-field magnetostriction and good mechanical properties [2,3]. It has been confirmed that magnetostriction of Fe-x at% Ga at x around 19 is very sensitive to the thermal history, which is directly related to the change of room-temperature phase constitution [4].…”
