Abstract

In order to study the microstructure of Fe-Ga alloy, Fe₈₅Ga ₁₅ ribbons prepared with different wheel velocity were studied by high resolution X-ray diffraction (HRXRD) and extend X-ray absorption fine structure (EXAFS). HRXRD patterns showed that only disordered A₂ phase was observed in as-cast Fe₈₅Ga₁₅ alloy. A modified-DO₃ phase was detected in all of the melt spun samples. The HRXRD associated with EXAFS results indicated that Ga atoms were located as second-nearest neighbor along [100] orientation. A little DO₃ phase was found in ribbons annealed at 1000°C under 0.06 MPa Ar atmosphere. The result of magnetostriction measurement revealed that in the ribbon prepared with higher wheel velocity, more modified-DO₃ phase will enhance the magnetostriction. DO₃ phase in the annealed sample will deteriorate the magnetostrictive properties of Fe-Ga ribbons.
