Abstract：Methods of measurement of Curie temperature of Fe-based amorphous ribbons using differential scanning calorimeter (DSC)and thermal dilatometer (DIL) were studied respectively，and the test results were analyzed and compared It shows that with appropriate test conditions, it can obtain obvious Curie transition signals The research of Curie transition of Fe-based amorphous ribbons show a angle bend on the DSC curves, while an abnormal expansion which is a contraction on the DIL curves It is found that the ending temperature of the contraction on the DIL curves is almost equal with the turning point on the DSC curves It is put forward that the ending temperature of the contraction which shows the Curie transition on the DIL curves can be considered as the Curie temperature The effect of heating rates on the test results were studied, and it is found that the heating rate faster than 10 K/min is needed for DSC method, while slower heating rate is suitable for DIL method In the suitable range, changing the heating rates has little effect on the test results of the Curie temperature
