Magnetic Properties and Substructure of Iron–Gallium Alloy Single Crystals Processed from Ingot to Wafers

To process ingots of Fe–Ga alloy single crystals into wafers, Fe–17% Ga were cut using multi-wire sawing or electric discharging and rolling. Further, their properties magnetization magnetostriction analyzed electron backscatter diffraction (EBSD) X-ray (XRD). It was observed that the curves changed with increasing rolling reduction. Although negligibly affected by deformation, shape curve as-grown crystal could be modified a slight reduction in plastic deformation. EBSD results show introduced dislocations to form heterogeneous dislocation cell walls decreased surface roughness wafers. The pole figures obtained XRD indicate samples crystals; however, orientation different from ideal after Residual stress measurements cos α method revealed compressive tensile stresses remained polycrystalline layers discharging, respectively. Moreover, strains magnetic fields when residual relatively small sample. are rolling, they not significantly reduced reductions.
