Gamma-irradiation influence on the initial magnetic conductivity of based on the system Fe-Si-B amorphous and nanocrystalline alloys

TL;DR

This study investigates how gamma irradiation affects the initial magnetic permeability of Fe-Si-B amorphous and nanocrystalline alloys, revealing increased sensitivity due to alloying and structural changes caused by radiation.

Contribution

It provides new insights into the radiation sensitivity of Fe-Si-B alloys and the structural mechanisms influencing magnetic properties under gamma irradiation.

Findings

Alloying with Ni and Mo increases radiation sensitivity of amorphous alloys.

Nanocrystalline alloys are less sensitive to gamma irradiation than amorphous ones.

Radiation causes non-magnetic inclusions in the alloy structures.

Abstract

The dependence of initial magnetic permeability {\mu}i of based on the Fe-Si-B amorphous and nanocrystalline alloys on the {\gamma}-irradiation dose was investigated by the method of inductance factor determination. It was determined that the alloying of amorphous Fe-Si-B alloys by nickel and molybdenum increases the radiation sensitivity of the {\mu}i. Initial magnetic permeability of nanocrystalline magnetic alloys is less sensitive to the action of {\gamma}-irradiation as compared with the alloyed amorphous alloys. Has been suggested that radiation influence on the initial magnetic permeability are caused by creation of non-magnetic incorporation in structure of amorphous alloys as well as amorphous matrix of nanocrystalline alloys.
