- the investigations also included a number of different KA charges of the alloy Fe 7 3, 5 Cui b 3 Sii 3 . 5 B 9 , in which the manufacturing parameters were varied with a view to improving the ductility in the production state. From these batches ring wire cores measuring 22 mm x 16 mm x bandwidth were also produced for magnetic investigations.

- Example 1 is based on investigations in terms of roughness and strip thickness with the alloy Fe75.5CuiNb3Sii2.5Bs as batch KA 1283
- the ratio of strip thickness to surface roughness d / R a ranges from about 10 to 60.
- FIG. 2 shows the associated variation of strip thickness d and surface roughness Ra. It can be seen in FIG. 2 that the thinner tapes as a rule also have an absolutely greater roughness.

- FIG. 5 shows the dynamic coercive field strength H c (as defined in FIG. 1) as a function of the ratio d / R a .
- Example 2 is roughness and tape thickness investigations with the alloy Fe 7 3, 5 Cui b 3 Sii 3 . 5 B 9 from different batches, as well as investigations of other influencing parameters. On different batches of alloy Fe 7 3, 5 Cui b 3 Sii 3 . 5 B 9 results are shown in Figures 7-11. Here too, the just discussed dependence of the magnet values on the band roughness and band thickness arises. In contrast to the case discussed above, here the influence of roughness is expressed somewhat more explicitly, since the mean
- the values of the static coercive field strength are about 3.5 mA / cm. This compared to the alloy of Example 1 Fe75,5Cui b3Sii2.5Bs significantly lower values is partly because ⁇ through implies that the static loop only about
- the 50Hz magnet values are in the present case
- a striking feature of the strip geometry was ei ⁇ ne more than 5 ⁇ deep longitudinal groove which was not maintained in Ra value ent ⁇ , ie it was not measured in the measurement over this ridge of time. This groove is due to slag particles in the nozzle, which eventually led to splitting of the belt and ultimately premature firing.
- FIG. 11 shows these changes as a function of the exciting field together with the BH commutation curve in comparison with Ultraperm 200. It can be seen that the changes in the soft magnetic nanocrystalline metal strip are significantly greater than in the case of the ultracrystalline Ultraperm 200 metal strip of a NiFe alloy ,
- Example 3 is based on investigations on an amorphous comparison material VITROVAC 6030 Z (Z stands for material with a rectangular hysteresis loop) with regard to roughness and strip thickness. For comparison with the nanocrystalline material show the
- a possible magnetization process with rectangular hysteresis loops is that the magnetization of the movement of 180 0 -Domänenroomn runs transverse to the strip longitudinal direction. Due to the associated strong spatial localization of the magnetization changes, excessive, so-called anomalous eddy current losses result. In this case, the greater the increase in losses, the fewer domains involved in the magnetization process.
- Designate p e i is the specific electrical resistance, n 0 is the number of domains per unit area during the quasi - static run through of the hysteresis loop,
- V 0 a minimum value by which the external field increases ⁇ the need to form a new domain, or to set an overall pinned wall in motion, V 0 is so last ⁇ Lich closely linked to the static coercive field strength,
- B is the induction amplitude
- H dB / dt The power loss is generally given by H dB / dt, where the rate of magnetization reversal dB / dt is proportional to f -B.
- H is the external field needed to compensate for locally generated eddy current fields. From equation (1) follows for this:
- H c sa (B) denotes the course of the quasi-static hysteresis loop, which is mainly due to
- Equations (1) and (2) The ultimate critical parameters in Equations (1) and (2) are the domain density n Q , as well as the nucleation field strength V 0 . To clarify below is how both sizes are related to the surface roughness and the strip thickness.
- d denotes the strip thickness
- K the anisotropy in the band longitudinal direction
- ⁇ an effective wavelength, which represents a measure of the extent and distance of the surface defects.
- H c stat in accordance with equation (5a) is proportional to R a / d, that is ultimately more dependent on R a / d than the anomalous eddy current losses. This results in inferior magnet values again due to the increasing hysteresis losses for bands that are too rough.
- H c is independent of surface defects In this case, H c is determined by nucleation or by pinning to intrinsic anisotropy fluctuations. Then with which the eddy current field as
- Ra follows. This case is particularly important for nanocrystalline work ⁇ materials, in which the average crystal anisotropy (K) can make a significant contribution to H c due to the finite particle size, in contrast to amorphous systems.
- K average crystal anisotropy
- the term K would have to be replaced by K u ⁇ Ki>.
- the 50 Hz characteristic of nanocrystalline (as well as amorphous) materials with a rectangular hysteresis loop is decisively characterized by anomalous swirling current losses.
- the above investigations indicate that the ratio of the strip thickness d to the surface roughness R a forms a significant influencing parameter, which can go far beyond the influence of the alloy composition.
- the best magnet values were found for ratios d / R a ⁇ 20, ie for thin bands (around 20 ⁇ m and smaller) with a relatively rough surface (R a around 1 ⁇ m or slightly larger).
- the alloy composition Fe 73 , 5 Cui b 3 Sii 3 .5Bg can be so in the for AC-sensitive
