知見した。Next, the effect of the tension will be described. The present inventors have noticed that when AC-excited a Fe-Co alloy plate annealed after cold rolling, the flutter (vibration) of the sample is extremely large as compared with other materials, particularly a silicon steel plate. When the flutter of the sample was large, accurate measurement could not be performed. Therefore, when the measurement was performed while holding the sample with a plywood, it was found that the characteristics were greatly changed depending on the degree of pressing force applied. Therefore, the soft magnetic properties were measured by applying various stresses to the sample. As a result, it has been found that the soft magnetic characteristics are dramatically improved by applying tension in the magnetization direction.

ことになる。FIG. 1 shows the effect of tension found by the present inventors. That is, FIG. 1 shows the relationship between the applied tension and the soft magnetic characteristics. FIG. 1 (a) shows the iron loss value, FIG. 1 (b) shows the maximum magnetic permeability at DC, and FIG. 1 (c) shows the magnetizing force. The magnetic flux density at 1 Oe (Oe) and the magnetic flux density at 0.1 Oe of magnetizing force are shown in FIG. The sample used in the experiment was prepared by ingot of Fe 49 wt%, Co 49 wt%, and V 2 wt% by vacuum melting, hot rolling to a plate thickness of 2 mm, and quenching to obtain a good processed material. This material was cold-rolled to a sheet thickness of 0.2 mm and then annealed in an H 2 atmosphere. At this time, the heating time during quenching was changed between 1 and 180 minutes. By applying a load between both ends of the sample with a small clamp and applying a tension of 0.5 kgf / mm 2, the maximum DC permeability is 2-3 times (Fig. 1 (b)), and the coercive force changes to less than half. . Also, the AC characteristics have been dramatically improved,
Iron loss at W 17/50, 2.0 w / kg is reduced to 1.0 w / kg, become oriented electrical steel sheet parallel. B 8 from 2 to 2.1T.
Improves to 2T. The magnetic flux density at a magnetizing force of 1 Oe is
The magnetic energy is improved from 1.5 T to about 1.9 T, and magnetic energy equivalent to that of a grain-oriented electrical steel sheet can be obtained with a magnetizing force of 1/10.

0.1kgf / mm is effective in practical use
It's more than two . When 2 kgf / mm 2 tension is applied, the effect of the present invention is saturated.
If it is less than the elastic limit, the effect will not be impaired. The elastic limit of this material was 80 kgf / mm 2 as a result of a tensile test. Therefore, the upper limit of the applied tension is set to 80 kgf / mm 2 .

であることが分かる。It has been conventionally known that grain-oriented electrical steel sheets improve soft magnetism by applying tension to the steel sheets.
However, this is due to the texture unique to grain-oriented electrical steel sheets.
The magnetic flux density of the grain-oriented electrical steel sheet is deteriorated by improving a core loss characteristic, for example, by having a tension coating.
In the case of grain-oriented electrical steel sheets, such an effect is remarkably recognized in the rolling direction, that is, the direction in which the (110) [001] orientations of crystal grains accumulate.
In the case of the system soft magnetic material, it was equally recognized in all directions in the plane of the steel sheet regardless of the texture. That is, it is understood that the effect of the present invention is different from the effect obtained with the grain-oriented electrical steel sheet.

The details will be described in the embodiment section, but an example is shown. As shown in FIG. 2, an alloy having a composition of 49% by weight of Fe, 49% by weight of Co, and 2% by weight of V was melted, and a ring 1 having an outer diameter of 45 mm, an inner diameter of 33 mm, and a thickness of 5 mm was formed by casting. 8 this ring
After heating to 50 ° C and thermally expanding, 5m length in the outer circumferential direction
A disk 2 having an outer diameter of 33.05 mm and a thickness of 5 mm having a notch 3 having a depth of 3 mm and a depth of 3 mm was fitted at room temperature. The sample is gradually cooled in the atmosphere, and the exciting coils 4 and 2 are inserted into the notches of the disk.
A small transformer was made by spreading the secondary coil 5. The maximum magnetic permeability at that time was 10,000. The maximum magnetic permeability when the same heat treatment was performed without inserting the disk into the ring sample was 5,500. This effect is the result of the effect of the present invention being exerted by the tension applied in the circumferential direction of the ring by so-called shrink fitting. As described above, the effects of the present invention have been confirmed not only for the steel plate-shaped sample but also for the block-shaped sample. The elastic constant of the material used at this time is 15

きた。[Table 1] When a tension film is attached to the surface of a steel sheet, surface tension is applied to the steel sheet. When this is processed into a ring shape, tension is applied in the circumferential direction of the ring, that is, in the direction of magnetization. When one side of the two samples corresponding to the present invention in the table was pickled and the coating was removed, it was observed that the steel sheet warped to the side from which the coating was removed. This means that the film tension was applied to the two samples. The film tension was calculated from the degree of warpage and the elastic constant of the steel sheet, and is shown in the table. Thus, a Fe—Co soft magnetic steel sheet having the effect of tension could be obtained.
