• 英文摘要： The effect of Fe, Si, C contents on the magnetic and mechanical properties and thermal stability ofFeBCSi and FeBCSi amorphous alloys has been studied. It is found that among FeBCSi alloys with 10≦ x ≦ 18, the FeBCSi alloy has the highest Curie temperature, crystalliza-tion temperature, and activation energy △E for initiation of crystallization, and the lowest core loss; forFeBCSi alloys with 0 ≦ x ≦7, replacement of carbon by silicon reduces the saturation magnetiza-tion and microhardness, but increases the Curie temperature, embrittlement temperature and activationenergy. Core loss measurements show that the core loss not only depends on the alloy composition differ-ence, but also heavily depends on the quenched and pretreated conditions of the prepared samples. Takinginto consideration all the physical properties studied, the FeBCSi alloy can be regarded as the mostsuitable one for use in power transformer, since it has high magnetic induction (B＝16.5 kG) and embrittle-ment temperature (T=377°C for 30 minute annealing), relatively low core loss (3.2×10 watt-sec/kg atB=12.5 kG), and good thermal stability (△E=2.61 ev).
