| Research on structure and magnetization losses made for bulk iron-based amorphous alloys are presented. Bulk alloys were made by injection casting in the form of rods with a diameter of 1 mm. Losses on remagnetization was tested after samples solidification. Samples had an amorphous structure. The dilatometric properties of the samples after solidification were also tested. These tests were performed at room temperature in the frequency range from 0 to 1000 Hz. Magnetostriction for this type of material should be close to zero, which results in almost complete removal of the double noise spectrum effect. One of the most important parameters determining the ability to use electrotechnical materials in transformers are losses due to magnetization and the associated effect of magnetostriction. Limiting these two side effects of the magnetization process of magnetic cores impacts environmental protection and economy. |
