摘要：
To study the thermal expansion of amorphous Fe-Si-B alloys, the amorphous Fe78Si9B13 and Fe73.6NB3Cu1Si13.5B9 and their crystallized alloys were detected using thermal dilatometer. The results indicate that at the same temperature, the relative length change (ΔL/L0) values of the two Fe-based amorphous alloys decrease with increasing heating rate, but those of their crystallized alloys show an opposite trend. It is concluded that the effect of heating rate on the ΔL/L0 of amorphous and crystallized alloys is related to free volume and defects, respectively.
