The microstructure and magnetic properties of alloy Fe₇₈Co₂Zr₈Nb₂B₉Cu₁ obtained by single roll melt spinning are studied after annealing at 550, 600 and 650°C for different times. In the case of annealing below 650°C the amorphous matrix contains only precipitates of phase α-Fe(Co). After the annealing at 550°C the specific saturation magnetization increases with the duration of the annealing; after the annealing at 600 and 650°C for over 30 min it remains the same.

热处理条件对Fe78Co2Zr8Nb2B9Cu1合金组织和磁性能的影响

研究了单辊熔纺获得的Fe ₇₈ Co ₂ Zr ₈ Nb ₂ B ₉ Cu ₁合金在550、600和650℃不同时间退火后的显微组织和磁性能。在低于 650°C 退火的情况下，非晶基体仅包含相 α-Fe(Co) 的沉淀物。550℃退火后，比饱和磁化强度随着退火时间的延长而增加；在 600 和 650°C 下退火超过 30 分钟后，它保持不变。
