Crystallization process and magnetic property of Fe81Zr3Nb6B10 alloy
2015
Fe81Zr3Nb6B10 amorphous alloy was prepared by melt-spinning and annealed at various temperatures. The thermal property, microstructure and magnetic property were investigated by differential thermal analysis (DTA), X-ray diffraction (XRD) and vibrating sample magnetometer (VSM). The crystallization process of Fe81Zr3Nb6B10 alloy is as follow: Amorphous → residual amorphous + α-Fe + α-Mn type → α-Fe solid solution. Coercivity (Hc) of Fe81Zr3Nb6B10 alloy changes complexly, which abruptly deteriorates at 843 K and then softens with increasing annealing temperature (Ta).
