A study of crystallization behavior and magnetic property of Co-based alloy
Source abstract
Abstract
The crystallization behavior and magnetic properties of Co-based alloy are investigated by DSC, XRD, TEM, VSM, and impedance analyzer. The results indicate that the non-isothermal crystallization of Co 50 Fe 25 Nb 15 B 10 alloy has a significant glass transition with a supercooled liquid region of about 80 K. When the heat treatment is above crystallization temperature, some phases appear successively as the Co 2 B and (Co, Fe) 21 Nb 2 B 6 , and with the increase of annealing temperature, the values of coercivity H c and saturation magnetic induction strength B s increase correspondingly. After measuring the impedance effect of the Co-based alloy, it is found that the increase in impedance value is attributed to the decrease in magnetic anisotropy performance of the alloy, and the impedance curves of both amorphous and nanocrystalline alloys show a similar single peak trend. However, the crystallization phases after annealing form with a large size that hind the magnetization process resulting in a significant decrease of (ΔZ/Z) max value.
