Enhancement of Thermal Stability and Bending Ductility of Fe–Si–B Amorphous Ribbons with Minor Y Addition

다국어 초록 (Multilingual Abstract)

The influences of minor Y addition on the thermal stability, crystallization behavior, magnetic property and bending ductilityof Fe–Si–B amorphous ribbons have been systematically investigated. The results show that all the ribbons with Y additionare fully amorphous structure, and the introduction of Y can enhance the glass forming ability of Fe–Si–B amorphous alloy.
With Y addition, crystallization temperature of the first and second phase shift to high temperature side, the temperatureinterval between the two crystallization peaks are enlarged, the third phase transitions process of Fe–Si–B amorphous alloywith Y addition corresponds to the precipitation of Fe3Bphase. The activation energy of the first and second phase calculatedby Kissinger’s formula increased with Y addition. Appropriate Y addition is beneficial for Ms. The measured coercivity Hcgradually decreased with the Y addition increased. The amorphous alloys exhibit good bending ductility in the quenchedstate. The ductile to brittle temperature increase to 300 °C with 1 at% Y addition. Furthermore, the mechanism of ductile tobrittle for amorphous alloy was discussed.
