The microstructure, preferred orientation and magnetostriction of Y doped Fe-Ga magnetostrictive composite materials

Optical Fiber Current Sensors Based on FBG and Magnetostrictive Composite Materials

“…When the pre-compression stress reaches 9 MPa, the composite material obtains the highest magnetostriction value. Xuan Zhao et al [26] studied the effects of magnetic field orientation and rare-earth elements on magnetostrictive composites. The author prepared two samples of the same composite material, one cured without applying orientation magnetic field, the other cured with orientation magnetic field.…”

“…Although the sensitivity of the composite material is lower than that of the monolithic alloy, the sensitivity and linear range of the sensor are increased by 40% and 20%, respectively, by applying 8.6 MPa preloading stress. Xuan Zhao et al [26] studied the effects of magnetic field orientation and rare-earth elements on magnetostrictive composites. The author prepared two samples of the same composite material, one cured without applying orientation magnetic field, the other cured with orientation magnetic field.…”

Flexible Pr‐Doped Fe–Ga Composite Materials: Preparation, Microstructure, and Magnetostrictive Properties

“…In addition, as shown in Figure 1, compared the XRD patterns of Fe 83 Ga 17 Pr x ( x = 0, 0.2, 1.0) OR composite materials with corresponding UN composite material, the relative intensity of (211) diffraction peaks increases in various degrees. The origin of this phenomenon was systematically investigated in our previous work, [ 21 ] the analysis indicating this phenomenon is caused by slip and rotation of crystal grain under applied magnetic field. And this rotation and slip of crystal grain will finally result in the formation of <100> orientation in OR composite materials.…”

“…The alloy powders obtained after ball milling were sieved by sieves with grids opening of 75 μm. This particle‐sized powder was used as raw materials as in our previous work, [ 21 ] the magnetostrictive properties of this particle‐sized composite material was the best. The Fe 83 Ga 17 Pr x ( x = 0, 0.2, 1.0) alloy powders were mixed with epoxy binder, to investigate the effect of weight ratio of magnetostrictive powder versus epoxy binder on the magnetostrictive properties of composite materials, we prepared different weight ratios of composite materials, and the weight ratios are 2:1 and 1:1.…”

“…If we use rare-earth-doped Fe-Ga alloys instead of the binary Fe-Ga alloys, it may obtain novel composite materials with better magnetostrictive properties than that of binary Fe-Ga composite materials. In addition, in our previous research, [21] the influence of particle size of magnetostrictive powder on magnetostriction properties of Y-doped Fe-Ga composite materials was investigated. Due to the low magnetostrictive properties of relatively high-content Y-doped Fe-Ga ((Fe 83 Ga 17 ) 97 Y 3 ), the magnetostrictive properties of (Fe 83 Ga 17 ) 97 Y 3 composite materials are limited, where the DOI: 10.1002/adem.202000080 Herein, the manufacture process and the results of investigations into the microstructure and magnetic properties of flexible Fe 83 Ga 17 Pr x (x ¼ 0, 0.2, 1.0) composite materials are presented.…”
