Novel FePCB nanocrystalline alloys induced by indium microalloying

In this work, novel Fe86-xP11C2B1Inx (x = 0, 0.2, 0.4, 0.6, 0.8 and 1) amorphous alloys were developed. After proper annealing of the amorphous precursor, Fe85.8P11C2B1In0.2 nanocrystalline alloy, with relatively low coercivity (Hc) and high saturation magnetization (Bs) in the range of 2.9-21.0 A/m and 1.63-1.73 T, was ob-tained. The structure of the nanocrystalline structure was investigated and confirmed by XRD and TEM. The results indicate that In microalloying can induce the nanocrystallization in FePCB amorphous alloy, which was proved by Kissinger's plot. It provides a new way to develop new Fe-based nanocrystalline soft magnetic alloys.

Automated summary

Novel Fe86-xP11C2B1Inx (x = 0, 0.2, 0.4, 0.6, 0.8 and 1) amorphous alloys were developed in this study. After appropriate annealing, Fe85.8P11C2B1In0.2 nanocrystalline alloy with low coercivity (2.9-21.0 A/m) and high saturation magnetization (1.63-1.73 T) was obtained. The nanocrystalline structure was confirmed by XRD and TEM, and In microalloying was found to induce nanocrystallization in FePCB amorphous alloy according to Kissinger's plot. This provides a new approach for developing Fe-based nanocrystalline soft magnetic alloys.
