铁基非晶合金具有铁损低、有效磁导率高等优点,广泛应用于传感器和执行器中。功率效率是功率转换应用中最重要的指标之一。比较了金属玻璃带FeCoSiB (Vitrovac 7600)和FeSiB (metglass 2605SA1)的磁力功率转换系数。我们研究了不同退火温度下的结晶过程,并通过共振和反共振方法测试了磁力耦合因子(k)和质量因子(Q)。结果表明,退火后Vitrovac带的最大耦合系数为23%,优点系数k2Q为4-7;退火后的metglass带的最大耦合系数为73%,k2Q最大值为16。我们可以观察到,metglass 2605SA1带比Vitrovac 7600带具有更高的磁机械功率效率值,这意味着它们更适合用于后续关于声驱动天线的研究。
Fe-based amorphous alloys have advantages of low iron loss and high effective permeability, which are widely used in sensors and actuators. Power efficiency is one of the most important indicators among power conversion applications. We compared the magnetomechancial power conversion factors of metallic glassy ribbons FeCoSiB (Vitrovac 7600) and FeSiB (Metglas 2605SA1). We investigated the crystallization process under different annealing temperatures and tested the magnetomechancial coupling factors (k) and quality factors (Q) by using resonant and anti-resonant methods. We found that the maximum coupling factor of the annealed Vitrovac ribbons was 23% and the figure of merits k2Q was 4–7; however, the maximum coupling factor of the annealed Metglas ribbons was 73% and the maximum value of k2Q was 16. We can observe that the Metglas 2605SA1 ribbons have higher values of the magnetomechanical power efficiency than those of the Vitrovac 7600 ribbons, which means they are better to be used in subsequent research regarding acoustically driven antennas.
