英文摘要	The amorphous Fe735Cu1Mo3Si135B9 alloy has been prepared and annealed at 793 K for different times. Mossbauer spectra, X-ray diffraction anal differential thermal analysis (DTA) measurements were employed to investigate the variation of microstructure during the isothermal annealing process. The results indicate that the crystallized fraction, hyperfine field of crystalline and amorphous phases, as well as the grain size are almost independent of the annealing time between 20 min. and 180 min., implying that a structural relaxation of interfaces may occur. The thermal relaxation of interfaces of nanocrystalline structure may be similar to that of amorphous alloys prior Co crystallization and therefore is stable to the isothermal annealing, implying an intrinsic stability of the nanocrystalline structure. The structural relaxation may be related to the arrangement of internal stresses and local defects. In view of this, a relationship with the soft magnetic properties of alloys is discussed.
