New algorithm for optimizing technological
parameters of soft magnetic composites has been derived on the base of
topological structure of the power loss characteristics. In optimization
magnitudes obeying scaling, it happens that one has to consider binary
relations between the magnitudes having different dimensions. From
mathematical point of view, in general case such a procedure is not
permissible. However, in a case of the system obeying the scaling law it
is so. It has been shown that in such systems, the binary relations of
magnitudes of different dimensions is correct and has mathematical
meaning which is important for practical use of scaling in optimization
processes. The derived structure of the set of all power loss
characteristics in soft magnetic composite enables us to derive a formal
pseudo-state equation of Soft Magnetic Composites. This equation
constitutes a relation of the hardening temperature, the compaction
pressure and a parameter characterizing the power loss characteristic.
Finally, the pseudo-state equation improves the algorithm for designing
the best values of technological parameters.
